Modern life is not without electricity, and now the common practice of home decoration is to bury the wire into the wall or the floor, so that the overall look and feel is more clean and refreshing. But the downside is that it's hard to detect changes to the wires, or repairs. And many people simply do not realize that the wire also needs to be maintained and updated, thinking that it will be OK. This is a big mistake. So what factors affect the service life of the wire? Today, Qingdao Tianxing

What is the effect of unqualified insulation thickness on the cable? What kind of sheath is qualified? How do we make qualified cables in production?

The computer cable ground wire core insulation is made of low density polyethylene with antioxidant properties. Polyethylene has high insulation resistance, good voltage resistance, small dielectric coefficient and the influence of dielectric loss temperature and variable frequency,

Computer cable belongs to electrical equipment cable, this cable is suitable for rated voltage 500V and below for high interference requirements of electronic computers and automation instruments.

Fire wire is the fire line of the emergency lighting or alarm system with the wire, different wire uses and characteristics are different, naturally match different electrical and instrument systems, Qingdao cable manufacturers to introduce the fire wire commonly used models.

The 70-year-old cable is suitable for all densely populated places, such as shopping malls, theaters, stations, airports and other public places, as well as important distribution lines, building wiring, home improvement and so on. The service life of this product is not less than 70 years at the average working temperature of 70℃. The allowable working temperature of the cable conductor for a long time is 90℃, 105℃, 125℃; The operating temperature of short circuit (5S) is 250℃.
