A kind of cold-resistant moving used flat cable
[technical field]
The utility model relates to field of cables, particularly makes the cold-resistant flat mobile cable of using of sheath and insulating barrier with acrylonitrile-butadiene rubber.
[background technology]
Mobile devices such as the driving of using in the low temperature environment in industries such as electric power, chemical industry boats and ships, harbour, chassis, transmit machine and electrical equipment require to use flexible (flexible) good, low temperature resistant flat cable with power transmission line and control, illumination, communication line.Flat cable oversheath and insulating layer material that tradition is used mainly are PVC (polyvinyl chloride), and PVC material flexural properties meets the demands, but cold tolerance is not good, and impact resistance is poor at low temperatures, thereby is not suitable for.
[utility model content]
Technical problem to be solved in the utility model is according to market demand, at the problem that present flat cable exists, provides outstanding cold-resistant the moving of a kind of performance to use flat cable, has lower temperature resistance, flexible good preferably, can adapt to bad working environment.
The utility model is to solve the problems of the technologies described above by the following technical programs: a kind of cold-resistant flat mobile with cable by three diameters identical and thin heart yearn group of diameter formed, described heart yearn group is pressed the arrangement of " one " font; It is characterized in that: described heart yearn group comprises lead, and described lead forms by the multiply copper free wire is stranded, and lead is surrounded by acrylonitrile-butadiene rubber insulating barrier and separator outward successively; The outside coextrusion acrylonitrile-butadiene rubber of described four heart yearn groups becomes outer jacket.
The utility model advantage is: have flexibility, pull resistance preferably, especially cold-resistant oil preventing performance is outstanding, cable insulation is difficult for hardening and becomes fragile under low temperature environment, strong shock resistance, be widely used in industries such as electric power, metallurgy, harbour, boats and ships, be mainly used in these industries exchanging that specified alternating voltage is low temperature resistant at 0.6KV and following needs, mobile device such as the driving of tension, specific (special) requirements such as wear-resisting, anticorrosion, chassis, transmit machine and electrical equipment is with power transmission line and control, illumination, communication line.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is a flat cable cross-sectional structure schematic diagram.
[embodiment]
Referring to Fig. 1, a kind of cold-resistant moving used flat cable, is made up of lead 1, insulating barrier 2, separator 3, outer jacket 4; Lead 1 forms by the multiply copper free wire is stranded, lead 1 outer acrylonitrile-butadiene rubber insulating barrier 2 and the separator 3 of being surrounded by successively, and lead 1, insulating barrier 2, separator 3 constitute an independent heart yearn group; Three described heart yearn groups and a diameter are pressed the yi word pattern arrangement than the slightly little heart yearn group of above-mentioned three heart yearn groups, and the outside promptly obtains this product by Nitrile Rubber coextrusion oversheath 4.
