Factors of affacting the improving cable technology

The application of new technology is related with performance, cost, environment protection, system security and useful time. The listed 7 aspects are current problem met in cable technology.

1. Protecting cables from white ant and mice. Venomous materials are used before,but now it has been prohibited. Now using of hard materials is an availalbe way.

2. Application of PBT material. Before it is just used as engineering plastic, but now it's the main material of optical fiber cable.

3. Marcketing of unleaded PVC cable material. In order to decrease the lead pollution, unleaded PVC materials is certain to be used.

4. Application of blaket. In order to pass the B type and A type fire test, cheap and high performance filler is applied.

5. Small size fire-resistant cable. Quality of mica tape, wrapping machine, parameter are the key factor that affecting the cable quality.

6. Low voltage car cable. PVC cable is still used the most in cars. But the developing trends to be thin.

7. Five core cable. The use of this cable will be increased gradually.
