Application of steel continuous casting machine and tapping machine,metallurgical industry,power plant furnace body,electric valve,mainvalve and other places of high heat source electrical equipment,instrument of power control and signal control connection.Thisproduct is super high temperature resistant,aging resistant,acidand alkali resistant,oil resistant,water resistant,excellent properties,such as not burn.
The long-term working temperature of 200~500 °C,short-term use can reach 800~1000°C.
Fire burning test (IEC 60331),under the condition of electricity,750 °C flame 3 hours,circuit is normalwork.
The lowest installation temperature:-60 °C,the fixed installationtemperature:-20°C.
Shielding type fire retardant cable is especiallysuitable for signal control and large current transmission.
