Ruitian Cables is a leading supplier of medium voltage XLPE cables.
The cables are designed to carry high earth fault currents comparable to the symmetrical fault currents of the system.
The 3-conductor A-type cables are equipped with galvanized steel wire armor.
Single-core cables are usually armored with a single layer of aluminium wire.
Conductor - Aluminum or copper
Conductor shielding - extruded semiconductor layer integration
Insulation - XLPE
Core screen - extruded free peelable semiconductor layer
Semiconductor numbered tape*
Metal ground shield - copper tape
Filler - Preformed Plastic Material*
Adhesive Tape

For reticulation, mining, underground power supply and house connections. Most of our low voltage cables have XLPE insulation. The cable is single wire armored (SWA), but can be manufactured unarmored. It is available as flame retardant (FR), low halogen cable (LHC) or halogen free cable (HFC). We stock copper and aluminum from 1,5 mm to 300 mm, from 25 mm to 300 mm.
Cross-linked polyethylene (XLPE) cables are used in underground reticulation, main distribution systems, substations and mining. Three-core cables come standard with Single Wire Armored (SWA), but can be manufactured unarmored. Single-core cable is either unarmored or has an aluminum wire armor (AWA). It is available as flame retardant (FR), low halogen cable (LHC) or halogen free cable (HFC). We mainly stock 25mm to 300mm 3 core copper 6,35/11kV, but can manufacture any size and voltage, including ultra high voltage cables (over 33kV).
Cross-linked polyethylene insulated power cables have many advantages over paper insulated cables and PVC insulated cables.
Cross-linked polyethylene cable has high electrical strength, mechanical strength, high aging resistance, resistance to environmental stress, chemical corrosion resistance, easy construction, ease of use, and high long-term operating temperature.
It can be laid without falling restrictions.
Cross-linked polyethylene cable has higher long-term operating temperature and higher current rating.
Under the same environmental conditions, the size (normal cross-section) of cross-linked polyethylene cable can be reduced by 1 or 2 steps compared with paper and PVC cables.
These not only improve the quality and performance of the product, but also reduce the cost of cable production.
These cables are typically used for direct burial applications in installation environments with free-draining soil conditions. They can also be installed internally.
