CN103904592A - Method for manufacturing 10 kV cross linked polyethylene insulated thermal shrinkage terminal - Google Patents

Abstract

The invention relates to the field of high-voltage cables in the metallurgical industry, in particular to a method for manufacturing a 10 kV cross linked polyethylene insulated thermal shrinkage terminal. The method comprises the steps of fixing the tail end of a cable, peeling and cutting the cable, welding a ground wire, installing a branch fingerstall, peeling and cutting a split-phase shielding and semi-conducting layer, installing a stress control pipe, pressure-welding an amphenol connector and installing an insulation tube, a slave tube and a phase color tube. The 10 kV cross linked polyethylene insulated thermal shrinkage terminal manufactured with the method enables construction to be conducted easily and conveniently and is simple in structure, convenient and fast to install, safe and reliable in insulating and shielding performance, good in sealing performance, and suitable for long-term use in severe environments.

Technical field

The present invention relates to metallurgy industry high-tension cable field, relate in particular to the crosslinked polyetylene insulated hot shrinkage terminal head of a kind of 10kV manufacture method.

Background technology

Become in distribution engineering in the modern times, cable is convenient with its construction maintenance, power supply reliability high is widely used, cable terminal collection waterproof, Stress Control, shield, electrically isolate from one, there is good electric property and mechanical performance, can under various rugged environment conditions, use for a long time, cable terminal is widely used in the every field such as electric power, petrochemical industry, metallurgy, but, existing cable terminal has complex structure, stability is poor, under rugged environment too, cannot move normally for a long time.

Summary of the invention

The object of the present invention is to provide the crosslinked polyetylene insulated hot shrinkage terminal head of a kind of 10kV manufacture method, solve the defect that prior art exists.

In order to realize above-mentioned object, adopt following technical scheme: the crosslinked polyetylene insulated hot shrinkage terminal head of a kind of 10kV manufacture method, it is characterized in that, concrete grammar comprises the steps:

S1. by cable end piece alignment, and be fixed on cable bearer, outdoor terminal is measured to 750mm by end, carve annular tool marks at the place of measuring;

S2. para-electric cable direction breaks plastic sheath, separately divests to both sides, upwards a little less than copper cash colligation armour for 30mm place, and cuts steel band at sheath mouth place, retains inner covering 20mm at steel band incision position, wins filler, separately core;

S3. braiding soft copper band one end is taken apart and divided equally three parts, again after braiding, hold respectively each phase screen and tie, be welded on copper strips, by one section between braiding copper strips and cable cover(ing), fill up the long 15-20mm in space between litzendraht wire and cable cover(ing) by design size with tin and form moistureproof section;

S4. hold and fill glue and make its flat appearance at three-phase crotch and root, pack into branch's fingerstall, itself and heart yearn root be close to, with slow fire annular from fingerstall root toward two ends first downwards backward upper heat shrink fix, after shrinking completely, end should have a small amount of glue to extrude night;

S5. by upwards 55mm copper shield place of branched bushing finger tip, use copper wire colligation, cut off mask tape, divest outer semiconducting layer, retain apart from copper shield opening 20mm outer semiconducting layer;

S6. be inserted in stress tube, more than stress tube bottom and copper shield are overlapped on 20mm, from top to bottom around to stress tube heating, make its contraction with low baking temperature;

S7. determine wire length E, divest main insulation, stripping end should be whittled into pencil head, crimping binding post, frustrated with emery cloth flat, with fill glue fill insulation and terminal between and load mould;

S8. by insulative to trident root, pipe is more than upper end answers superfill glue 10mm, by up heat shrink insulated tube unnecessary terminal is cut off after heating of root;

S9. looped pipeline is enclosed within to terminal and takes over position, first pre-hot terminal, plays heat shrink by upper end, is then inserted in phase colour tube and takes over heat shrink at terminal;

S10. clean insulating surface, is inserted in three hole full skirts, and heat shrink behind location is installed single hole umbrella skirt, and heat shrink after being rectified, in the installation of carrying out adjutant and phase colour tube.

Compared with prior art, the crosslinked polyetylene insulated hot shrinkage terminal head of 10kV of the present invention is simple and easy to do, simple in structure in construction, and it is convenient to install, and the performance safety of insulation and shielding is reliable, and good airproof performance, is suitable in the situation that environment is severe, working for a long time.
