Therefore, the wires and cables mainly applied with high-temperature vulcanized silicone rubber include power cables, ship cables, heating cables, ignition cables, atomic energy device cables, aviation wires, etc. In silicone rubber used in high-voltage insulated circuits, the addition of aluminum hydroxide fillers can enhance the rubber's resistance to tracking, erosen bilong lektrik, na arc.
