Products:

　　Rated voltage plastic insulated copper 0.6/1kV prefabricated branch cable can be widely used in residential, office buildings, hotels, hospitals, shopping malls, factories, and other power distribution systems. The main cable conductor, connector, extension cable conductor joint structure is reasonable, minimal contact resistance, thermal expansion and contraction are not affected. And has excellent shock resistance, good air tightness and water resistance, wet environment in the normal power supply, can also be laid in the open air and buried. Small area of ​​floor space, is conducive to the efficient use of floor space, easy to install.
　　Products, the enterprise standard Q/320282GADl3, standard reference used GBl2706 and JISC2810 standards.
　　Allow long-term working temperature of cable conductor is: XLPE insulated 90 ℃; 70 ℃ PVC insulated
　　Allow short-circuit temperature of cable conductor: XLPE 250 ℃, the duration of no more than 5 seconds.
　　　　　　　　　　　　　　　　　　　　　　　　　PVC insulated 160 ℃, the duration of no more than 5 seconds.
　　Flame retardant cable can effectively prevent the spread of flame; low smoke zero halogen cable does not produce toxic gases when burned, produces only a small amount of smoke; fire resistant cables in the 750-800 ℃ (or 950-1000 ℃) under fire conditions, can be maintained Running 90min.

　　Standard trunk cables and extension cables are based on models with the corresponding insulation and sheath materials, with reference to IEC, GB, JIS and other standards made ​​of low-voltage power cable. General Cable is a single trunk or multi-core twisted (two core five-core cable), Extension cable with single core cables. The structural characteristics are as follows:

1、Non-fire resistant cable structure

• 
  Single-core cable
• 
  Four core twisted cable

2、Fire-resistant cable structure

• 
  Single-core cable
• 
  Five core twisted cable

3、The structure of the branch connector
　　Prefabricated branch cable connection part of the body using special PVC or synthetic materials, such as cable connections shown on the right branch of the body.
