HIGH VOLTAGE CABLE

High voltage cable

Veri Cable provides a comprehensive range of high voltage cable, which includes XLPE underground insulated power cable, and overhead power line.

Veri Cable is committed to becoming a world-class provider of voltage cable.

Depending on the different international standards, our standard lv cables, mv cables and high voltage cables are designed for the primary distribution of power on networks.

As the hv cables, it can be divided into aluminum high voltage cables and copper high voltage cables according to different materials.

With the complex environmental conditions and special requirements in areas, the use of copper core cables is more reliable in terms of quality and safety.

According to our construction, the selection of cable models should refer to the surrounding environment, the corresponding means of laying, and the performance of electrical equipment.

Types of Veri High Voltage Cable

High voltage power cable

XLPE Insulated Armoured High Voltage Power Cables

The type of high voltage power cable is designed for distribution of electrical power with nominal voltage 35kv/220kv.

They are suitable for installation mostly in power supply stations, indoors and in cable ducts, outdoors, underground and in water as well as for installation on cable trays for industries, switchboards and power stations.

High voltage power cable

APPLICATION​

As a type of high-voltage cable, its suitable for the primary distribution of power up to a maximum network voltage of 220kv, and the application of trunk transmission is relatively high.

And the conductors can be made of copper or aluminum, depending on customer’s preference or current carrying capacity.

There are usually two kinds of armor layers for cables, steel tape armor and steel wire armor.

In order to protect the structural integrity and electrical performance of the cable and improve the service life of the cable, it is very necessary to add an armor layer to the outer sheath of the cable.           

STANDARDS&REFERENCES:IEC 60840
  • Conductor: copper or aluminium
  • Conductor Screen: Extruded layer of semi-conducting cross-linkable compound
  • over the conductor and shall cover the surface completely
  • Insulation: cross-linked polyethylene compound XLPE
  • Insulaton Screen: semi-conducting cross-linkable compound
  • Separation Sheath: Aluminum Tape sheath
  • Outer Sheath: PE

High Voltage Aluminium Conductor Steel Reinforced Cable

Aluminium conductor steel reinforced overhead cable mainly used in power transmission lines with high voltage.

Its advantages include high mechanical strength, good electrical conductivity, corrosion resistance, light unit volume, easy erection, high-temperature resistance, simple structure, convenient installation, good maintenance, and large transmission capacity.

The conductor of ACSR consists of a solid or stranded steel core surrounded by strands of aluminum.

APPLICATION​

The type of these cables uses in electricity distribution lines laying across rivers and valleys where special geographical treatures exist. The conductor of ACSR represent the most important component of an overhead power line because they have to ensure economical and reliable transmission and contribute considerably to the total line costs.

  • Conductor: aluminium
  • Street lighting conductor: Round standed or compacted Aluminium conductor
  • Insulation: LDPE/HDPE/XLPE/PVC

Laying of Veri High Voltage Cables

Inspection before cable laying: whether the model and specifications meet the requirements, the insulation should be good, the appearance should be complete, and there should be no traces of trauma.

A spare length should be reserved near the cable terminal, and a spare length should be reserved for the directly buried cable in the wave-shaped laying.

The distance between each fulcrum of the cable shall be as specified in the design.

When there are no design regulations, it should not be greater than rubber cable and plastic cables are horizontal 1M, vertical 2M, and cables suspended on steel cables are horizontal 0.75M.

The bending radius of the cable should not be less than 10 times the outer diameter of the cable (armored or unarmored multi-core plastic insulated power cable).

When laying the cables, the cables should be drawn out from the upper end of the reel, and avoid friction and drag of the cables on the bracket and the ground.

The cables should not be crossed when laying, they should be neatly arranged, fixed, and signs should be installed.

There should be firm stakes at the corners of the directly buried cables. When cables enter cable trenches, tunnels, buildings and pipes, the entrances and exits should be closed.

Clamps and fixtures for AC single-core cables should not have a closed magnetic circuit composed of iron.
