High performance long life wire and cable in the initial investment cost is higher than ordinary halogen-free low smoke flame retardant (refractory) wire and cable, but according to the 50 years of service life of the building, the cable does not have to replace the cable in the service life of the second cost, and ordinary cable service life is only about 30 years, the need to replace the cable twice in the service life of the building, there is no economic comparison. For complex and diverse buildings such as super high-rise buildings, the cable design selection should try to use high-performance long-life wire and cable, which can not only better meet the relevant requirements of the design, but also save the trouble of replacing the cable twice.

In the early stage of electrical design of super high-rise buildings, whether the relevant parameters of high-performance long-life wire and cable can meet the requirements of relevant national norms and standards, whether it can be verified by thermal stability, mechanical strength, voltage loss, and whether it is more economical than the initial investment and long-term income should be considered as the content and basis of electrical design.

Rated voltage 450/750V double-layer co-extruded insulated radiation cross-linked halogen-free low-smoke flame retardant (fire-resistant) wire [referred to as WDZ(N) -GYJS(F)/125], the product manufacturing standard is JG/T 441-2014 "Rated voltage 450/750 and below double-layer co-extruded insulated radiation cross-linked halogen-free low-smoke flame retardant wire", Because of its good safety, energy saving and environmental protection, coupled with stable aging resistance and long service life, it is called high-performance long-life wire and cable.

(1) Double-layer insulation structure design, irradiation crosslinking process.

(2) The life of the cable is synchronized with the building, and the service life is more than 70 years.

(3) The cable has low-voltage halogen-free flame retardant, anti-aging and other characteristics, the cable combustion will not release halogenated acid and other toxic and harmful gases, will not produce "dioxins" harmful substances, will not cause "secondary pollution", the cable does not contain heavy metals, is environmentally friendly products.

(4) The mechanical and physical properties and electrical properties of the cable are excellent.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable, computer cable, BV wire and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
