Aluminum alloy conductors originated in North America and have been widely used as cable conductor materials since the 1970s. Aluminum alloy conductor cables have been widely used in residential, commercial, industrial and military projects due to their advantages of safety, reliability, stable operation, and high cost performance. At present, more than 80% of low-voltage product applications in Europe and the United States are aluminum alloy conductor cables, and 40% of medium-voltage cable products are aluminum alloy conductor cables.
Low-smoke free-halogen flame-retardancy wire cables can produces little smoke and inno cuousgas without halogen or with little halogen when combustion. It can extremely reduce the damage to the instruments,equipment and body as the fire occurred .So, itwas widely used in the crowded public concourses such as high-rise building, large-sized library,gymnasium, commanding&dontollingbuilding for guard against blast,station, ivil airfield, passenger waiting room,emplases cultural relic,subway,underground shop,etc.
1)The long-time working temperature of cable should not be higher than 70℃. 2)When core is in short-circrit (max 5s)the temperature should not excced 160℃.
Isolation type (flexible) mineral insulated fire-resistant cable NG-A (BTLY) WDZAN-BTLY, NG-A, BTLY, WDZN-BTLY. Our company can also produce low smoke halogen-free and flame-retardant fire-resistant cables of the above models.
YTTW,YTGW series of new metal sheathed inorganicmineral insulated flexible fire-proof cables adopt advanced productiontechnology, fully automated mechanized production, reliable product quality, meet JG/T313-2011 "rated voltage 750V and belowmetal sheathed inorganic mineral insulated cables and terminals" product industry standards. This kind of product has beenrecommended by the Chinese Architectural Standard DesianInstitute of the Ministry of Construction.
This product is suitable for automatic control, monitoring, circuit protection and other systems with rated AC voltage of 450/750V and below. Fixed installation in indoor environments in industries such as metallurgy, power, and construction.
Low smoke and halogen-free wires and cables produce a very small amount of smoke during flame combustion, and the released gas does not contain halogen (low halogen) elements, making it non-toxic (low toxicity). When a fire occurs, it can greatly reduce the harm to low-level equipment, devices, and human health.
Bending radius of single core cable is 20(d+D)±5%Bending radius ofmulti-core cable is 15(d+D)±5%D=Aetual outer diameter of cable sample(mm)d=Aetual diameter of the comductor(mm)
