LN-5Z(不锈钢带) 防水阻燃型可挠金属电线保护套管
LN—5Z(不锈钢带)防水阻燃型可挠金属电线保护套管
LN一5Z(NCr)Water Proof＆Prevent Burning Type
LN-5Z(不锈钢带)防水阻燃型可挠金属电线保护套管，其结构规格与LN—5相同，PVC用优质耐温阻燃级，防火性能强。适用于室内外潮湿防火要求较高的电力导线配管，用干桥梁、隧道、造船、电厂、高档建筑等的明、暗预埋和直埋的配管，更可替代地面线槽布线用管等。
LN-5Z (Ncr) and waterproof casing flame retardant protection Prica metal wires. LN-5 compliance with the same structure, temperature flame retardant PVC quality level, strength of fire,apply to indoor and outdoor fire damp demand for a higher power distribution control cable for bridges tunnels, shipbuilding plant that the high-grade construction, and buried secretly embedded in the piping wiring can be replaced with ground trough, etc
