Using low-grade materials under such environmental stresses will cause the cable sheath to be fragile and even decompose the cable insulation. All of these situations directly increase the loss of the cable system and the risk of short circuits in the cable.It will also increase, and in the medium and long term, the possibility of fire or personal injury will also be higher.
This kind of cable has non-flammable,smokeless,non-toxic and fire-resistant characteristics. The process structure of flexible mineral insulated fire-proof cable(BBTRZ) is exactly the same as that of traditional cable, which successfully solves many shortcomings of products determined by the production process of magnesium oxide copper pole mineral insulated cable (BTTZ).
YTTW, YTGW series of new metal sheathed inorganic mineral insulated flexible fire-proof cables adopt advanced productiontechnology, fuly 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 beerrecommended by the Chinese Architectural Standard Design Institute of the Ministry of Construction.YTTW and YTGW series products have excellent fire protection performance. The fire resistance grade not only satisfies theinternational GBl2666.6A class 980 ~C, but also meets the requirements of Class A 650 ~C 3h, Class B 750 ~C 950 ~C 3Hstipulated in B$6387-1994. At the same time, they can also withstand water spraying and mechanical impact in combustion.
The utility model is a fire-proof cable with novel structure, safe and reliable productquality, good fire-proof performance, large carrying capacitly, good flexibilitly, long production length, corrosion resistance andconvenient installation and laying.
BTLY insulated (flexible) mineral insulated cables are all made up of inorganic substances (copper and magnesium oxidepowder),
The inorganic compounds used in cable materials are allinorganic compounds,so this kind of cable has non-flammable,smokeless,non-toxic and fire-resistant characteristics.When a fire occurs,the ceramized silicone rubber becomes a hard ceramic shell,which plays a role of fire prevention and heat insulation.
Rated voltage 35kV and below, copper-core and aluminum-core cross-linked polyethylene insulated power cables: GB/T12706-2020, GB/T1966-2019, IEC60502
The performance of cross-linked polyethylene insulated (flame-retardant) power cables complies with the national standard GB/T12706-2020, and their flame-retardant properties comply with the national standard GB/T1966-2019.
The product is used in aerial electric circuit at AC rated voltage U(Um)-10(12)KV.
Type KVVP₂,ZR-KVVP₂450/750V Copper Conductor PVC Insulated and Sheathed Control Cable with Copper Tape Shield Type KVVP₂,ZR-KVVP₂450/750V Copper Conductor PVC Insulated and Sheathed Control Cable with Copper Tape Shield
This product is suitable for rated ac voltage 450/750V or below domestic appliances,power-operated tools and various portable electric equipments.
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.
