Main features of silicone rubber high temperature wire

The main features of silicone rubber high temperature wire are high temperature resistance, insulation, flame retardant, acid and alkali resistance, aging resistance, weather resistance, high strength, high modulus, antistatic, and smooth surface. High temperature insulated wires include fluoroplastic insulated wires, silicone insulated high temperature wires, high temperature electronic wires, silicone insulated wires, multi-core high temperature wires, PEEK wires and mineral insulated fire-resistant cables. PTFE high-voltage wire, PTFE wire, nylon sheathed wire, mica high temperature wire, aircraft lacquer wire.

The quality of the silicone rubber high temperature cable can be seen at a glance by the appearance of the cable. Appearance requirements of silicone rubber high temperature wire: smooth and round, uniform gloss, no visible debris, no mechanical damage, no flattening, no deviation from the core wire (not exceeding the specified deviation), bubble sand holes, bamboo knots, twisted shapes, particles Wait. It can be seen that the quality of the silicone high-temperature wire is affected by the thickness of the sheath. The thickness of the sheath is of course unqualified, and if the thickness exceeds the standard, it is also unqualified.

The material properties of silicone rubber high temperature wires are based on standard requirements rather than thickness. If some indicators cannot meet the standard, it will directly affect the quality of the silica gel high temperature wire. After the silicone rubber high-temperature wire is laid, it will be energized for a long time to generate heat energy. The allowable working temperature of the wire is 70°C, and the allowable long-term working temperature of the silicone high-temperature wire is 180°C. In summer, the temperature will increase. This temperature is dissipated through the housing. The thickness of the sheath will increase, and the heat energy will not be easily dissipated, which will affect the service life of the silicone high-temperature wire. Under the action of heat, the thermal insulation material will undergo a series of physical and chemical changes, lose its original excellent performance, make its insulation performance drop significantly, or even short-circuit, affecting the normal operation of the unit.
