Special fire-resistant cable
Description
I. Overview: Special fire-resistant cable, High temperature resistance 800 degrees refractory cable flame does not burn refractory wire YW500 (350℃ ~ 1000℃) electric furnace, oven, wire star breaker, pure nickel wire -60-1000℃ rated temperature :500℃ ~ 1000℃ rated voltage :750V- special refractory cable, special refractory glass fiber braided shielded cable, The conductor is a single or twisted wire with 0.5 to 25mm2 of bare copper, nickel plated, or pure nickel wire. The insulation is made of natural mica tape wrapped, glass fiber woven, high temperature mica glue vacuum sintering high temperature, color red, blue, white, yellow, green, brown, black (the general color is milky yellow). The length of delivery is allowed to be no less than 10 meters short section of wire delivery, the quantity of which cannot exceed 20% of the total quantity delivered. Chemical plant use refractory wire can be added stainless steel braided mesh, can be used in corrosion resistance, wind proof, wear resistant and other harsh environment.
Two, application: applicable to metallurgy, petroleum, chemical industry, oven, boiler, power plant, fire facilities, civil electric furnace, natural gas, furnace and other high temperature environment, the need for fire performance of all kinds of electrical equipment cable. This product is produced in accordance with enterprise standards. Products for iron and steel metallurgy, petrochemical, power plants, nuclear power plants, aerospace household appliances, industrial boilers, fire sensing and other rated AC voltage 750V below the electrical equipment for wire and cable. The working temperature is 350℃ ~ 1000℃, the insulation resistance is not less than 400MΩ/m, the bending radius is 100, and the ambient bottom temperature is -60℃.
