NGABTLY four-core low-voltage power cable is a new generation of mineral insulated cable developed on the basis of BTTZ cable, which has the advantages of BTTZ cable and overcomes the problems and defects of BTTZ cable. Since the production length is not limited, no intermediate joint is required. The NG-A series fire-resistant cables comply with British standards: the rated voltage class is up to 0.6/1kV, and the BTL series mineral-insulated cables can operate normally with seamless metal bushings even if they are completely submerged in water. NG-A series high mechanical strength fire-resistant cables are strong and durable. In the design of refractory layer structure, considering the various effects that may occur under fire conditions, its fastening performance is better than that of steel tape armored cable. The metal sheath of NG-A series refractory cable has high corrosion resistance, and the working temperature of NG-A series refractory cable is lower than other types of cable, so the BTL series mineral insulated cable has low line loss during normal operation and saves energy consumption, which is especially suitable for application in projects with environmental protection requirements. The metal sheath of the NG-A series fire-resistant cables has high corrosion resistance, and for most equipment, no additional protective measures are required; Offshore oil platforms, aerospace, iron and steel metallurgy, shopping centers, parking lots, general lighting, emergency lighting, fire alarm, fire electrical lines, emergency elevator and lifting equipment lines, computer room control lines, trunk distribution system lines, dual power control lines, potentially dangerous explosion area lines, fire monitoring systems, fire alarm systems.
