flame retardant cable compounds
- Usage
This product is suitable for use in all places using non-com-bastion-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
1.Rated voltage(U0/U), from 300/300V to 26/35KV according to different kinds of product series.
2.The max. word temperature of cable for a long period are:70°C, 90°C and 105°C.
3.For short circuit(5s), the max. work temperature of conductor does not exceed 160°C for 70°C;250°C for 90°C.
4.The temperature for laying cable is not less than 0°C.
5.Cable bend radius implements corresponding non-com-bastion-retardant cable standard stipulation.
6.Combustion-retardant characteristics can be divided into categories A and C(category B is not recommended).
a.ZC-type combustion-retardant cable is used in general combustion-retardant places requiring IEC60332-3C category.
b.ZA-type combustion-retardant cable is used in combustion-retardant places requiring relatively harsh IEC60332-3A category.
c.Single cable should reach the requirement of IEC60332-1(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 IEC60332-3 standard and will extinguish itself.
- Scope of Application
Nuclear power station, underground railway, telecommunications station, high rises, petroleum, metallurgy, power plant installations, tunnel, etc.
