Detailed Product Description

*Features and applications of product

The product is a modified one that is researched and developed by our company recently on the basis of original cable for frequency conversion electric equipment produced by our company and absorbed precious suggestion from customers and referring cable manufacturing standard and normal. Now it has been applied state patent and granted and got patent license. The product adopts the form of compound shield which can withstand strong electrostatic coupling, electromagnetic induction, electric wave, bad grounding and conduction interference of main lead. When circuit arise current component of higher harmonic and side frequency harmonic, the sum of current at shielded layer will be zero. Therefore it cant produce interference to outside. The product is suitable for frequency control transmission device of roll machine and power line and transmission and distribution line where has strict shielded requirement with 0.6/1kv and below. It is widely used for metallurgy industry, power industry, petrochemical industry, etc.
