the conductor is composed of 1-10 copper wires which are soft in texture, and the copper wires are mutually separated;
the filling layer is filled with high-temperature-resistant thermosetting elastic silicon gel, and is filled around the conductor to play a role in heat insulation, because the high-temperature-resistant thermosetting elastic silicon gel can resist 1200 ℃ or even higher temperature, and also can play roles in dust prevention, insulation, heat insulation, corrosion prevention, high temperature resistance and shock prevention.
The first insulating layer is made of a polytetrafluoroethylene material, and further, the thickness of the first insulating layer is 2mm to 3 mm. This is chosen because polytetrafluoroethylene is a heat-resistant thermoplastic polymer, can withstand high temperatures of at least 300 ℃, is excellent in electrical resistance, corrosion resistance and weather resistance, and is non-toxic.
The temperature resistant layer is woven by glass fiber yarns and then coated with non-combustible paint, because the material woven by the glass fiber yarns has the advantages of high strength, light weight and corrosion resistance, the flame retardant temperature can reach 850 ℃, and the high temperature resistant characteristic of the cable can be further enhanced.
The second insulating layer is made of polytetrafluoroethylene materials, and further the thickness of the second insulating layer is 2-3 mm.
The protective sleeve is arranged at the outermost end and formed by winding a plurality of layers of fire-resistant mica tapes, and further, the protective sleeve is formed by winding 3-5 layers of fire-resistant mica tapes, and the thickness of each layer of mica tape is 0.4-0.5 mm. The mica tape is selected as the sheath because the fire-resistant mica tape has high resistance, can bear 5000V high voltage without breakdown, does not burn at high temperature of 1000 ℃, and does not age after long-term use.
