The cable comprises one high-voltage transmission line, a metal braided shielding layer, an isolating layer, a plurality of signal transmission lines, fillers, belting layers and outer protective layers, wherein the metal braided shielding layer is coated on the high-voltage transmission line; the isolating layer is lapped on the braided shielding layer; the signal transmission lines are stranded outside the isolating layer; the fillers are filled inside gaps among the signal transmission lines; the belting layers are lapped on the signal transmission lines and the fillers; and the outer protective layers are coated on the belting layers. The high-voltage transmission line includes a conductor, a silica gel insulated layer, a glass silk braided layer and a silica gel insulated layer, wherein the former silica gel insulated layer is coated on the conductor; the glass silk braided layer is coated on the former silica gel insulated layer; the latter silica gel insulated layer is coated outside the glass silk braided layer; and both the glass silk braided layers are made of high insulation performance silica gel. Each signal transmission line includes a conductor and a fluorine material insulated layer coated on the conductor.
Description
Technical field
The utility model relates to a kind of anti-crooked high pressure composite cable, refers in particular to the hv transmission line of alternating bending use and the composite cable that signal transmssion line is combined, the cable used as electrostatic storage deflection (ESD) test.
Background technology
Conventional hv transmission line is independent use, because hv transmission line can produce high temperature when carrying out several ten thousand volt high voltage transmission and powerful Harmonic Interference is outwards propagated, environment around the influence, interference when particularly high voltage pulse transmits is severe more, and electronic equipment and signal of communication are all had very big influence.Signal transmssion line withstand voltage not high, antijamming capability is also limited, generally will keep certain distance with hv transmission line for preventing hv transmission line to its interference.The general alternating bending of hv transmission line is used high-voltage breakdown is very easily taken place, and therefore generally all adopts hard-wired hv transmission line.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of and can alternating bending uses and anti-50KV and the hv transmission line of following direct voltage and the high pressure composite cable that signal transmssion line is combined into.
The technical problem that the utility model solves is achieved by the following technical solution: cable comprises a hv transmission line, be coated on metal knitted screen on the hv transmission line, wrapped on woven shield separator, be stranded in some signal transmssion lines described separator outside, enrich the filling, wrapped at signal transmssion line with the outer jacket of the belting layer of filling, coating belting layer in space between the signal transmssion line.Described hv transmission line comprises conductor, be coated on silicone insulation layer on the described conductor, be coated on the glass braid on the described silicone insulation and be coated on the outer silicone insulation layer of described glass braid, and described silicone insulation layer is high insulating property silica gel.Signal transmssion line comprises conductor and coats the fluorine insulated with material layer of described conductor.
Wherein the conductor of hv transmission line adopts flexible stranded conductor, and appearance requirement is shaped, and so promptly even high voltage electric field can also keep cable that good bending property is arranged.
The metal knitted screen that is coated on the hv transmission line adopts zinc-plated or the silver-gilt copper wire braiding, and count should be greater than 80%, the interference that produces in the time of well masking hv transmission line work like this.
The serving that coats belting layer is selected soft polyvinyl chloride or polyurethane material for use, can provide excellent protection to the cable core of combining.
Relative prior art, the utility model cable adds the insulation of glass braid structure as hv transmission line in the middle of adopting double-deck silicone insulation, make hv transmission line that good high voltage performance and resistance to bend(ing) energy be arranged, with other material ratio, under identical insulation thickness, it is high a lot of that the withstand voltage degree of this structure is obviously wanted, and also have good resistance to bend(ing) energy, can prolonged and repeated bending use; Signal transmssion line can not disturbed by hv transmission line in the utility model cable; The utility model cable has changed client's installation and occupation mode, and two cables are merged into a cable, and is easy to install and use, succinctly attractive in appearance after the installation.

Embodiment
With reference to the accompanying drawings, hv transmission line conductor 1 is twisted together by stranded conductor to be formed, conductor 1 is coated by silicone insulation layer 2, silicone insulation layer 2 outer braiding one deck glass braid 3, glass braid 3 is outer by 4 coating of silicone insulation layer, utilize the high withstand voltage properties of the high-insulation performance of silica gel, wide withstand voltage properties, soft resistance to bend(ing) energy and glass braid, form an anti-bending of softness, the withstand voltage hv transmission line that reaches the 50KV direct voltage.At silicone insulation layer 4 surface weave layer of metal woven shield 5, mainly play shielding action again, it is good to need only metal knitted screen 5 ground connection during use, the interference that produces when falling hv transmission line work with regard to maskable.Metal knitted screen 5 outer wrapped layer of non-woven fabric bands are as separator 6.Signal transmssion line conductor 7 is twisted together by stranded conductor to be formed, and conductor 7 is outer by 8 coating of fluoroplastic insulation layer.Some signal transmssion lines (in the accompanying drawing being eight) are stranded in outside the separator 6 by stranding equipment, middle space is filled 9 with polypropylene and is full of, make cable shaped, wrapped again layer of non-woven fabric band is as belting layer 10 outside signal transmssion line and filling 9, the belting layer 10 outer soft polyvinyl chloride outer jackets 11 of one deck that coat have so just been realized an anti-crooked high pressure composite cable.
