Description
Technical field
The utility model relates to technical field of wire cable manufacture, is specially a kind of two core heat resistant type sheath copper cables.
Background technology
At present, peel to prevent sheath, when producing copper cable, normally used sheath isolated material is medical talc powder, in the process of processing, easily produce dust, be detrimental to health, cause environmental pollution, in addition, when using medical talc powder to make isolated material, sheath is with epoxy resin in conjunction with insecure, processing difficulties, and along with the requirement of people to operational environment is more and more higher, the weatherability of traditional jacketed cable under high temperature, low temperature environment and load capacity all have much room for improvement.
Utility model content
The purpose of this utility model is to provide a kind of two core heat resistant type sheath copper cables, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of two core heat resistant type sheath copper cables, comprise ellipticity restrictive coating, two complex copper heart yearn A and B be set up in parallel are provided with in restrictive coating, complex copper heart yearn A coordinates the inwall of restrictive coating to be fixed in the middle part of restrictive coating by complex copper heart yearn A and complex copper heart yearn B with complex copper heart yearn B by cable core, cable core is I-shaped shape, its two end faces contacted with complex copper heart yearn A with B are arc-shaped, and match with the surface of complex copper heart yearn A and B; Complex copper heart yearn A comprises: copper cash, polyimide insulative enamelled coating, lubricating layer, thermal insulation layer and wear-resisting screen, described copper cash comprises copper cash main body and the pliable and tough bar of copper cash, the cross section of described copper cash main body is cross, four concave surfaces that the pliable and tough bar of described copper cash is separately positioned on copper cash main body match with four concave surfaces of copper cash main body, on described copper cash, uniform ring is wrapped is wrapped with one deck polyimide insulative enamelled coating, between polyimide insulative enamelled coating and thermal insulation layer, uniform ring is wrapped is wrapped with one deck lubricating layer, and on described thermal insulation layer, uniform ring is wrapped is wrapped with the wear-resisting screen of one deck.
Further, the structure of described complex copper heart yearn A with B is identical with size.
Further, the thickness of described polyimide insulative enamelled coating is 2 ~ 4mm.
Further, described wear-resisting screen comprises silicon rubber overcoat and the aluminium alloy net at the outer armouring of silicon rubber.
Further, described copper cash main body is red copper wire, and the pliable and tough bar of described copper cash is bronze wire.
Further, described restrictive coating is made up of silastic material.
Compared with prior art, owing to employing polyimide insulative enamelled coating, so characteristics such as high, resistance to freezing, cold-resistant, the radiation hardness of thermal endurance of the present utility model, electric property is stablized simultaneously, and overload capacity is strong; Because the utility model have employed lubricating layer structure between polyimide insulative enamelled coating and thermal insulation layer, make toughness of the present utility model high, and durable; And silicon rubber overcoat coordinates aluminium alloy net armouring, good shielding action can be played, too increase the stability of copper cable internal structure and the ability of resistance to extreme temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of two core heat resistant type sheath copper cables of the utility model.
In figure: 1-restrictive coating, 2-cable core, the wear-resisting screen of 3-, 4-thermal insulation layer, 5-lubricating layer, 6-polyimide insulative enamelled coating, the pliable and tough bar of 7-copper cash, 8-copper cash main body.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of two core heat resistant type sheath copper cables, comprise ellipticity restrictive coating 1, two complex copper heart yearn A and B be set up in parallel are provided with in restrictive coating 1, complex copper heart yearn A coordinates the inwall of restrictive coating 1 to be fixed in the middle part of restrictive coating by complex copper heart yearn A and complex copper heart yearn B with complex copper heart yearn B by cable core 2, cable core 2 is in I-shaped shape, its two end faces contacted with complex copper heart yearn A with B are arc-shaped, and match with the surface of complex copper heart yearn A and B, to reduce unnecessary space in copper cable, reduce air and enter, the structure of described complex copper heart yearn A with B is identical with size, complex copper heart yearn A comprises: copper cash, polyimide insulative enamelled coating 6, lubricating layer 5, thermal insulation layer 4 and wear-resisting screen 3, described copper cash comprises copper cash main body 8 and the pliable and tough bar 7 of copper cash, the cross section of described copper cash main body 8 is crosss, four concave surfaces that the pliable and tough bar 7 of described copper cash is separately positioned on copper cash main body 8 match with four concave surfaces of copper cash main body 8, on described copper cash, uniform ring is wrapped is wrapped with one deck polyimide insulative enamelled coating 6, the thickness of described polyimide insulative enamelled coating 6 is 2 ~ 4mm, between polyimide insulative enamelled coating 6 and thermal insulation layer 4, uniform ring is wrapped is wrapped with one deck lubricating layer 5, on described thermal insulation layer 4, uniform ring is wrapped is wrapped with the wear-resisting screen 3 of one deck, described wear-resisting screen 3 comprises silicon rubber overcoat and the aluminium alloy net at the outer armouring of silicon rubber, described copper cash main body 8 is red copper wires, and the pliable and tough bar 7 of described copper cash is bronze wires, and restrictive coating 1 is made up of silastic material, silicon rubber has good weatherability, in extreme temperatures, can normally be operated in-100 to 300 DEG C of environment.
