Power cables are mainly used for power transmission and distribution purpose. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. The assembly is used for transmission and distribution of electrical power. Electrical power cables may be installed as permanent wiring within buildings, buried in the ground and run overhead or exposed.……Including: rubber cable, welding cable, URD cable, XLPE insulated power calbe etc.
Bare Overhead Conductors are used in overhead transmission and distribution network applications.They are also used for un-insulated hook ups, jumpers, grounding conductors and other applications. Our Conductors conform to ASTM, IEC, BS, BS EN and DIN standards.…… Including: AAC conductor, AAAC conductor, ACSR conductor, ACAR conductor, AACSR conductor, etc.
Aerial bundled cables (also aerial bundled conductors or simply ABC) are overhead power lines using several insulated phase conductors bundled tightly together, usually with a bare neutral conductor. Our abc calbe conform to ASTM, IEC, SANS standards.……Including: abc cables, cvered line wire, service drop wire etc.
This product is applicable to the rated voltage of 500V and below high anti interference of electronic computers and automatic connection cable. Cable core conductor insulation adopts K type B class low density polyethylene with anti oxidation property.
Structure and use characteristics of computer cable:
1, conductor material: copper conductor, (1 types single conductor, 2 class 7 pieces cross conductor, 3 types multistrand conductor)
6, sheath material: Black PVC sheath, temperature range: 0- 70℃
7, AC rated voltage U0/U:300/500V; cable conductor term allows maximum operating temperature: polyvinyl chloride insulated 70 ℃, 105℃; polyethylene insulation is 70℃; cross-linked polyethylene insulation is 90℃ (cross-linked insulation types can be classified as silane cross-linking, radiation cross-linking).
8, the lowest ambient temperature: fixed laying -40℃; non-fixed laying: -15℃. installation ambient temperature: not less than 0℃.
9, allowed minimum bending radius: metallic tape wrapped shielding or steel wire and steel tape armored cable is not less than 12 times of cable diameter; non – armoured flexible cables or braided shielding cables are not less than 6 times of cable diameter.
In order to reduce the mutual interference between the circuit and the external disturbance, the cable adopts the shield structure. The shielding requirement of the cable is to be used in different occasions, such as the combination of the twisted pair, the total shielding of the twisted pair and the total shielding of the twisted pair combination. Shielding materials are round copper wire, copper strip, aluminum strip / plastic composite tape three. The shielding pair has better insulating performance with the shield, and if the cable is in use, if the potential difference between the shielding pair occurs, the transmission quality of the signal can not be affected.
