Insulation determines the quality of the wire?

There are many electrician master said: "To choose a good wire, is to pick the insulation layer." Do you agree? Indeed, the quality of the wire depends largely on the performance of the insulation layer, because the insulation layer plays a role in protecting the wire, such as: anti-breakdown, high temperature resistance, aging resistance, flame retardant, low dielectric coefficient and so on.

Disadvantages of PVC insulation layer

Insulation layer material is mainly made of plastic, the general market wire used insulation layer material is PVC, PVC in performance and cost control is a cost-effective insulation material. However, the performance of PVC wire is still weak, such as temperature resistance, PVC wire temperature range of 70~90℃; In addition, the stability of PVC to light and heat is poor, in continuous high temperature or long-term exposure, physical properties will rapidly decline, which is why the wire will age.

The risk of wire aging is very large, the insulation layer is damaged, and the electrical fire is often a hidden danger. Therefore, the insulation layer of the wire should also have flame retardant and fire retardant performance to block the occurrence of electrical fires. At present, flame retardant wires on the market are added on the basis of PVC insulation layer flame retardant or mica tape.

What should a good insulation have?

First, in the manufacturer's production process to have a low core rate, qualified process;

Second, the insulation layer should have the performance characteristics of high temperature resistance, aging resistance, corrosion resistance, flame retardant and fire prevention.

Traditional wire PVC material due to its performance limitations, it is difficult to have the above mentioned excellent performance, therefore, Tianxing wire in the research and production of wire insulation layer using higher performance than the traditional PVC material made of special plastics. The advantage of this special plastic is that it is an inert material, which is not easy to react with oxygen, and has excellent high temperature resistance, corrosion resistance, aging resistance and other properties; In addition, it is a V0 grade natural flame retardant plastic, that is to say, this material itself has excellent flame retardant and fire performance, without adding other flame retardants or mica tape and other materials.

In general, good wire, the premise is to have a good insulation layer. A good insulation layer can extend the service life of the wire, prevent electrical fire hazards, etc., to ensure our daily electricity safety.
