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.
Metal sheath has two main functions:
1. water barrier function: to prevent XLPE insulation contact with water to water-treeing, the metal sheath is radial water-resistant layer of cable;
2. can accept the zero sequence short-circuit current thermal stability is good. According to the production process can be divided into three categories: squeeze seamless metal sleeve, longitudinal weld metal sheath and integrated jacket, etc.
The materials used are lead, aluminum, copper and stainless steel, etc.
Manufacturing and structural characteristics of metal sleeve:
Seamless lead sleeve by continuous press lead machine extruding seamless continuous lead sleeve
Lead chemical stability, corrosion resistance
Corrugated seamless lead set by continuous or non continuous pressure machine aluminum extrusion aluminum sleeve and rolling corrugated cable weight light, with active chemical properties of aluminum, external sheath damage after aluminum sleeve perforation and larger diameter
Weld corrugated aluminum sleeve for welding aluminum volume after rolling again, but has longitudinal seam
Weld corrugated copper sleeve copper roll for welding after the corrugated longitudinal seam, the larger outer diameter
Turnkey welder welding and corrugating longitudinal seam weld stainless steel corrugated stainless steel plate, thermal stability capacity than longitudinal copper sets of low and larger diameter
Comprehensive sheath PE aluminum foil composite film longitudinal lap cover wrapped hot air welding cable, light weight, aluminum foil waterproof layer, the copper wire shielding meet thermal stability.
