Combustion-Retardant Cable&Wire Serial Products

Combustion-Retardant Cable&Wire Serial Products

Product Standard

Enterprise standard. At the same time ,apart from implementing IEC 332 for combustion retardant characteristics, products also adopt state standard ( GB/T) for non-combustion-resisting type equivalent to the products.

For example: Combustion-retardant power cable adopts equivalent standard GB/T 12706-2008.

Combustion – retardant installing wire and cable adopts equivalent standard GB/T 5023-2008 .

Usage

This product is suitable for use in all places using non-combustion-retardant type power cable , electrical equipment-use wire and cable and all corresponding products and at the same time requires combustion-retardant environment and conditions.

Property for Use

a. Rated voltage (U0/U), from 300/300 KV to 2

6/35 KV AC-cording to different kinds of product series .

b. The max. work temperature of cable for a long period are : 70℃,90℃ and 105℃ .

c. For short circuit( 5S) , the max. work temperature of conductor does not exceed 160 ℃ for 70 ℃ : 250℃ for 90℃.

d. The temperature for laying cable is not less than 0℃.

e. Cable bend radius implements corresponding non-combustion . Retardant cable standard stipulation.

f. Combustion – retardant characteristics can be divided into categories A and C(Category B is not recommended) .

α. ZRC-type combustion. Retardant cable is used in general combustion. Retardant places requiring IEC 332-3C category.

β. ZRA-type combustion . Retardant cable is used in combustion-retardant places requiring relatively harsh IEC 332-

3A category.

γ. Single cable should reach the requirement of IEC332-1(2) non-burning , that is , self – extinguishing nature . Multi- cable or a bundle of cable will only burn in a certain scope after reaching the IEC 332-3 standard and will extinguish itself.

Type and Specification.

Hui you cable is a mature power cable factory in China. Our Combustion Retardant Power Cable is mainly featured in low liability of fire or that second combustion is only limited to a certain range, meets the IEC60332 combustion testing requirements, and is applicable to the places with flame retardant requirement. 35V Combustion Retardant Cable is also hot selling in 2018.
