Abstract
The utility model belongs to the technologic field of electric apparatus, and relates to an improvement on the special type cable insulated by Teflon. The utility model comprises a conductor 1, an insulated layer 2 that wraps the conductor 1, a shielded layer 3 that wraps the insulated layer 2, and a sheath 4 that wraps the shielded layer 3. The utility model is characterized in that the sheath 4 is made of a silicon rubber. The utility model has the advantages of heat resisting, cold resisting, corona protection, arc resistant, little brittleness, well softness, ozone senescence resisting, oxygen senescence resisting, light ageing resisting, air ageing resisting, no water absorption, no algae and fungus growing, good mildew proof, and radiation resisting, which is especially suitable for the area of aviation and space industry.
Description
Technical field
The utility model belongs to the electrical equipment technical field, relates to the improvement to the teflon insulation special cable.
Background technology
The outermost sheath of present employed teflon insulation special cable adopts polytetrafluoroethylene membrane or FEP to make, and its shortcoming is: the wrapped sheath poor sealing of polytetrafluoroethylene membrane, and non-watertight, radiation resistance is poor, and the cable roundness is not enough.FEP extrudes sheath, and cable fragility is bigger, and not soft, resistance to cracking is poor.
Summary of the invention
The purpose of this utility model is: propose a kind of good airproof performance, water resistance is good, and radiation resistance is good, and cable softness, fragility are little, the teflon insulation special cable that resistance to cracking is good.
The technical solution of the utility model is: the teflon insulation special cable, form by the insulating barrier 2 of conductor 1, parcel conductor 1, the screen 3 of wrap insulate layer 2 and the sheath 4 of parcel screen 3, conductor 1 is silver-plated copper twisted wire or nickel-clad copper twisted wire or tin-coated copper twisted wire or does not have the coating copper stranded conductor, insulating barrier 2 is teflon insulation layers, screen 3 is metal wire knitted screens, it is characterized in that, are silicone rubber jackets at said sheath 4.
The utility model has the advantages that: can overcome the above-mentioned shortcoming of existing cable, specifically:
1, heat-resisting cold-resistant.
2, anti-corona, anti-electric arc.
3, cable fragility is little, very soft.
4, anti-ozone aging, oxygen aging, light aging, atmospheric aging.
5, do not absorb water, various algae and mould are not had the effect of growing, mildew resistance is good.
6, radiation hardness is specially adapted to aerospace field.
