TVVB, elevator control cables accompanying

Accompanied by an elevator control cable certification: CCC certification application is installed elevator control cables accompanying cable range with special structure design, long life, to maximize the operating efficiency of the elevator manufacturers. Elevator control cables in the case of longer length hanging provide total electrical control, simultaneously subjected to mechanical stress. Elevator bearing steel wire cable because the cable core can be used to fly long distances using the occasion. Elevator control cables accompanying feature using the new special cold flexible outer sheath may remain soft at -15 ℃ low temperature. Elevator control cables accompanying structure Conductor: fine strands of oxygen-free copper wire, insulation standards meet the VDE0295CLASS 5: special mix PVC insulation color: color representation, in line with GB5023.6 (yellow, white, orange, green, pink) Digital No. (without yellow-green grounding wire) liner: None stiffener: high-strength galvanized steel wire aviation (optional); Sheath: special cold-resistant PVC jacket, gray (RAL7001) or black (RAL9005) (do not) Rated Voltage: 300 / 500V: Test voltage: 2500V static bending test: 0.3m vertical burning test: Through GB / T18380.1-2001, IEC60332-1: 1993 Test: Product Standard: GB5023.6, lEC60227-6, EN5021 4 . Elevator control cables accompanying Guidelines for the use in normal use, the maximum temperature of 70 0c conductor cable suitable at -1 5 ~ + 400c of the environment: As the elevator usage follows an elevator cable is shaped arrangement 1, free to use When should consider increasing the load-bearing element in the cable, the load-bearing element is generally galvanized mild steel wire rope or fiber rope such as aramid yarn elevator cable is twisted plum-type arrangement; length greater than 35m; 2, run faster than 1.6m / s 1, free-hanging length greater than 80m; 2, running at 4.0m / s ~ 10.0 m / s; should consider increasing the load-bearing element in the cable, the load-bearing element is generally galvanized mild steel wire rope.
