Xlpe cables are one of the most advanced high voltage cables that are widely used today. This cable, which has many features, stands for the following words:
The letter X of the word Cross means cross, L stands for Link and PE stands for polyethylene.
High voltage cables, known as high voltage cables, are used to transmit electrical energy at high voltages. These cables are among the most used in the market and can transmit voltages of more than 20kv.
Uses of XLPE cables
This type of cable is used in construction and underwater services for trays and channels. It should be noted that these cables are also known as Crossling.
Components of high voltage cable
- Copper or aluminum conductor
- Semiconductor layers to equalize electric fields
- Ayl or main cover of XLPE material
- Shield to eliminate noise and magnetic fields
- Sheath or post PVC
Differences between XLPE and PVC
- The maximum temperature of cables with XLPE and PVC sheaths is different. This is the maximum for PVC cables 70 Celsius and XLPE sheathed cables 90 degree.
- PVC coated cables are more resistant to moisture.
- If the cable sheath is made of PVC, it has flame retardant properties, but XLPE does not.
- The life of cable with XLPE coating is longer than that of PVC cables.
Reasons for using XLPE cables
The high pressure cable can be used aerially, which has increased the use of this type of cable, and on the other hand, the costs of digging the ground and other things should be reduced.. This issue has made this type of cable to be used if there is a need for electric current with a voltage of more than 20kv.
In addition, these cables cause less damage to the environment and can be very effective and useful. Another feature of this type of cable is its quick and easy installation. Also, XLPE cables have ISO standards.
