Detailed Description

Cross-linked PVC insulation power cable not only has excellent electric and mechanical properties, but also has powerful resistance against chemical corrosion, heat-aging and environmental stress. Its structure is simple and can be used conveniently and also can be laid with no restriction of different levels. The long term operating temperature is 700C, and its transmission capacitance is large.

Our company can produce both flame retardant and non-flame retardant series of PVC power cables. Our products can be produced according to our works specifications which are equivalent to GB12706, IEC60502, IEC60332, IEC60754, and its some indexes are superior to standards as stated above..

The flame-retardant cable covers all kinds of low-smoke, free-halogen, low-smoke halogen free and three classes of A, B, C. We can design and manufacture special PVC cables according to the other standards require by the customers, such as heavy section cut part conductors, water-resistant, defend termites, defend mouse, and so on.
