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.
The power cable is usually used for long-distance power transmission, so its length is longer, which is equivalent to the line between the cable core and the insulating layer produces a large capacitance to the ground in the cable, the flow will be generated when the large current, pose a threat to people and facilities along, so in practice installation and operation requirements of the external steel armored cable for good ground connection, as is the capacitor current through the grounding line to drain into the earth, reduce the influence of the surroundings, when grounding bad connection or disconnect the capacitor current will exist between the heating cable and steel armored cable, is easy to cause heating, can lead to the decrease of the level of cable insulation.
Armoured cable shielded twisted pair (for RS485 & CAN), the cable OD is about 12.3mm, black sheath. Can be used for frequent and serious interference, rodent lightning protection, explosion-proof requirements of the place. When using, that armor layer grounded at both ends, the inner shield is grounded!
How to grounding shielded twisted pair cable?
Cable surface has Xibe metallic inclusions package cable conductor, prevent the interference of external electromagnetic field, in the terminal is introduced and grounding, in the middle must connect two ends by wire or Xibe, to ensure that the electromagnetic interference shielding effect.
