The Application of cable
It is used as vertical difference protection & power distribution devices to transmit various signals in electrical applicance & instrument, telecommunication, wave-carrier communication and high-frequency signal, which is installed with high-voltage cable in furrow or water ground.
Technical Demands
1. The conductor should comply with the stipulations in GB/T3953-1997, the surface of TR round CU wire should be clean and smooth, without oxidization stain.
2. The surface of PE insulation should be clean, smooth and neat.
3. The Min. pull for each conductor insulation≥2N.
4. The average elongation at break for conductor insulation≥300%.
5. The environment temperature for cable installation should be no less than -5oC, bending radius: A armored cable--It should be no less than 30 times that of cable outer diameter and it should 15 times for B cable without armor.
