Special refractory cable
Description
I. Overview: Special refractory cable, YW500 (350℃ ~ 1000℃) electric furnace, oven, wire nester, pure nickel wire -60-1000℃ Rated temperature :500℃ ~ 1000℃ Rated voltage :750V- special refractory cable, special refractory glass fiber braided shield cable, The conductor is a single or twisted 0.5 ~ 25mm2 bare copper, nickel plated or pure nickel wire. Insulation is made of natural mica tape wrapped, glass fiber woven, high-temperature mica glue vacuum sintering, red, blue, white, yellow, green, brown, black (general color is milky yellow). Delivery length is not less than 10 meters of short wire delivery, the quantity should not exceed 20% of the total delivery quantity. Chemical plant use refractory wire can be added stainless steel braided net, can be used in corrosion resistance, wind resistance, wear resistance and other harsh environment.
Two, application: suitable for metallurgy, petroleum, chemical industry, oven, boiler, power plant, fire protection facilities, civil electric furnace, natural gas, furnace and other high temperature environment, the need for fire performance of all kinds of electrical equipment required cables. This product according to the enterprise standard production. Products used in steel metallurgy, petrochemical, power plant, nuclear power plant, aerospace household appliances, industrial drying boiler, fire sensing and other ac rated voltage below 750V electrical equipment wire and cable. Operating temperature 350℃ ~ 1000℃, insulation resistance ≥400M ω /m, bending radius 100, ambient temperature -60℃ is still flexible.
Three, can replace refractory wire:
