Development of Flame Retardant Class B1 MV Fire Resistant Power Cable
In order to provide more time and security for emergency rescue and personnel escape in the event of a fire,a flame retardant class B1 MV fire resistant cable is developed.The use of the insulation core structure design of conventional MV power cables has met the requirements for MV power transmission performance.The use of the dense extruded structure of a high-temperature resistant and flame retardant insulation layer and a high-temperature crust ceramic fire insulation layer has met the requirements of 750℃fire resistance performance.The use of the alkali free glass fiber filling with excellent flame retardancy,high-temperature resistance,and heat release ability,as well as the specialized halogen-free,low smoke,flame retardant,and low toxicity polyolefin sheath material,has met the performance requirements of flame retardant class B1.The successful self-development of this type of cable meets the usage needs of high-rise buildings,various large public facilities,and shopping malls.
