Abstract

For jointing and terminating electric cables, (5, 6) particularly elastomeric cables comprising a core around which there is extruded an elastomeric insulating material, a method is provided which makes use of preformed tubular sleeves of elastic material (9, 10, 20) loaded as appropriate to provide desired electrically insulative, conductive, or anti-tracking properties etc. which can be rolled, folded or otherwise layered upon a supporting carrier (21) so as to be fittable over the cut end of a cable to be jointed or terminated and can readily be unrolled, unfolded, or unlayered etc. from the carrier onto the jointed/terminated cable end so as to provide a build-up of layers providing the requisite characteristics both axially and transversely of the cable joint. <IMAGE>

Description

SPECIFICATION Improvements relating to jointing and/or terminating electric cables This invention concerns improvements in jointing and/or terminating of electric cables and particularly, though not exclusively, is concerned with the jointing and/or terminating of elastomeric cables wherein the conductor insulation comprises an elastomeric material which is commonly extruded directly onto the conductor core in manufacture of the cable and one or more screening and/or other layers are commonly provided overlying the elastomer.

As is well known, jointing and/or terminating of such elastomeric cables requires removal of some of the cable layers over a length of the cable, the length of these layers removed being dependent upon the method of jointing and/or terminating employed. Removal of the screening layer or layers gives rise to electrical stresses at the cut end, and the jointing and/or terminating methods employed must take account of these and must incorporate measures to reduce the stresses to acceptable levels. Early jointing and/or terminating procedures required the building up of the cable profile at the joint or terminal location by lapping with tapes and the incorporation of electrically conductive windings of wire or metal foil or tape which were coupled to the cut-back cable screen.Subsequent developments employed pre-moulded stress cones formed of epoxy resin material for building up the joint or termination profile, and even more recent developments specifically intended for use in jointing and/or terminating elastomeric cables have provided preformed components of elastomeric material intended to be interference fitted to the cable, such components incorporating semiconductive layers to be made electrically continuous with the cable screen for stress relief purposes.

Preformed components of elastomeric material intended simply to be slipped onto the cut-back cable end at a joint or termination location are described for example in British Patent Specifications1 031 942, 1113841 and 1124 912 of Elastic Stop Nut Corporation of America; 1 042 590, 142 050 and 1196 989 of N.V. Nederlandsche Kabelfabrieken; 1 277 217 of Sumitomo Electric Industries Ltd.; and 1 339 502 and 1 348 048 of Amerace Esna Corporation. A disadvantage of such components is that, to accommodate the many different cable sizes which are available, a large range of component sizes must be provided.

Disadvantages arise also in accommodating variations in cable size resulting from manufacturing tolerances.

Another fairly recent proposal has been to use heat-shrink sleeves for cable jointing and terminating as described for example in British Patent Srpecification No. 1 475 292 (Raychem Corporation) and in British Patent Specification No. 1 526 397 (Raychem Limited). Proposals have been made to effect stress control in the use of heat shrinkable sleeves by incorporating materials into the heat shrink polymer such as to provide advantageous electrical properties. While the use of heat shrinkable sleeves has proven generally satisfactory, difficulties can arise on account of operator error resulting in there being voids left in the joint or termination.

Another disadvantage which has manifested itself in the formation of joints, particularly multicore joints, by use of preformed and heat shrinkable components is that, by virtue of the necessity to be able to pass a number of tubular components along the cable to be brought back subsequently to the joint location as the joint is assembled, a greater length of the outer cable layers has to be cut back than is desirable and the joint tends to occupy a longer length of cable than is strictly necessary or desirable.

The present invention resides in the concept of building up joints and/or terminations by use of tubular sleeves of appropriate elastic materials, such as rubber or elastomer, having such a degree of elasticity and such dimensions as to enable the sleeves to be stretched to a sufficient degree to enable them to be fitted. The sleeves can conveniently be rolled, folded or layered upon themselves and may be supported on a disposable carrier enabling them readily to be fitted onto the cable simply by threading the cable through the carrier and unrolling or unfolding the sleeve from the carrier into its desired position on the cable. The materials of which the sleeves are fabricated can have dispersed therein substances such as to provide desired electrical resistance or conductivity characteristics, anti-tracking characteristics, etc.

The invention, together with features and advantages thereof, will best be understood from consideration of the following description in conjuction with the accompanying drawings wherein: Figure 1 shows an exemplary cable joint constructed in accordance with the present invention; Figure 2 shows a tubular sleeve of elastic material rolled upon itself from each end towards the middle and supported upon a disposable carrier; and Figure 3 illustrates the way in which sleeves provided as in Figure 2 but only single rolled from one end may be utilised in the construction of a cable joint as shown in Figure 1.

Referring first to Figure 1, there is shown therein a joint between two elastomer insulated cables each comprising a central conductor 1, elastomeric insulating material 2, a semiconducting elastomeric material or varnished tape screen 6, and a wound metal tape screen 4. Other parts of the cable, not shown in the figure, might as is well known comprise a PVC or tape bedding layer overlying the screen 4 and providing a bedding for armouring wires, and a PVC outer sheath. The cable,may be single or multicore. As shown in the figure, the conductor ends of the two cables are secured, for example by crimping, in a metal ferrule 5, the insulation 2 having been cut back to bare the conductor ends.Similarly, the screens 6 and 4 have been cut back to a predetermined extent and a semi-conducting varnish screen 3 applied for stress relief purposes at the termination of screen 6.

As shown, a stress relief tube 7 is applied to each cable end, the tube 7 comprising for example an elastomeric material loaded with Silicon Carbide for example providing a non-linear electrical resistance characteristic. Semiconductive material 8, in the form of a lapping of a self bonding plastics tape for example or an appropriate mastic compound, is provided around the ferrule 5 and in the spaces between the ends of the ferrule 5 and in the cut-back insulation 2 of each cable. Then, as shown, two electrically insulating layers 9 and 10 are provided each comprising an elastic tube, of rubber for example, and finally a semi-conducting layer 11 comprising a tube of elastic material loaded with carbon for example is provided on the outside of the joint.

The tube 11 could be incorporated into the insulating layer 10 as an integral layer thereof, and more or less than the two insulating layers 9 and 10 could be provided.

Figure 2 shows an elastic material sleeve 20 rolled upon itself from each end and supported upon a disposable carrier 21 provided with weakened portions 22 around a central line so as to enable the carrier readily to be broken into two halves which can be extracted and cut off of the cable. The sleeve 20, having been appropriately positioned relative to its desired final position in the finished joint and the carrier 21 having been removed, can be unrolled into place. As will be appreciated, rather than being rolled, the sleeve 20 could be concertina folded on the carrier 21 or layered back and forwards upon itself. The carrier 21, as shown, is of greater diameter at each end than at its middle which serves not only to assist in retaining the sleeve 20 against its elastic tendency to unroll, but also facilitates threading of the carrier over the cable.The rolling up of the sheath 20 onto the carrier 21 can be effected at the factory or at the jointing site.

Figure 3 illustrates an intermediate stage in the formation of the jdint of Figure 1. The figure shows the two insulation layers 9 and 10 being unrolled along the joint from left to right, each layer comprising a single rolled-up tube as opposed to the double rolled-up configuration of Figure 2. It is only necessary to thread the rolled up layers onto the cable ends in appropriate sequence, and the joint can be cpmpleted simply by unrolling the tubes over the top of one another.

By virtue of the use of elastic tubular sleeves in the joint construction, variations in joint geometry can readily be accommodated and fewer components are required to be stocked to enable a range of cable sizes to be jointed. The method of the invention does not require the excessive cutting back of cable screening layers etc. which is the hallmark of other jointing techniques, and enables short neat joints to be produced with minimal risk of defects through operator error. No heating is required to perfect the joint which avoids the risk of overheating with resulting damage to cable integrity.

Whilst the invention is most advantageous in the jointing of cables where overlong joints are a problem with the conventional jointing methods, the invention is also applicabie to cable termination.

The invention is of course not limited to use with elastomeric cables, but can be used for jointing and/or terminating paper insulated cables and various other cable constructions, and for the making of transition joints between dissimilar cable types.
