Aluminum core XLPE insulated PVC sheathed, armored flame retardant cables for tunnel

• Aluminum core XLPE insulated PVC sheathed, armored flame retardant cables for tunnel
• Product Standard
  

Enterprise standard. At the same time, apart from implementing IEC60332 or GB/T18380-2001 or the GB306-2007 the Public Safety industrial Standard for combustion retardant characteristics, products also adopt state standard (GB) for non-combustion-resisting type equivalent to the products.

• 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℃, 90℃ and 105℃.

3.For short circuit(5s), the max. work temperature of conductor does not exceed 160℃ for 70℃;250℃ for 90℃.

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

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.
