In this post, XLPE power cables exporters and manufactures will explain the structural design and benefits of their products in detail. You can read this post and find out more info on power cables.
XLPE is a short for of cross linked polyethylene. Polyethylene is having a linear molecular structure as shown in below image A. Molecules of this material are not chemically bonded and it is shown in image B. This is why molecules are easily deformed at high temperature.
However, XLPE molecules are bonded in a three dimensional network as shown in image C and D. This is why XLPE molecules have strong resistance to deformation even if the temperature is high.
Manufacturers produce cross linked polyethylene from polyethylene under extreme pressure using organic peroxides as additives. The application of pressure and heat is used to effect the cross linking.
Benefits of using XLPE power cables-
- Ease of installation
XLPE cable withstands smaller radius bending. It is also lighter in weight and thus, the user never feels difficulty in installing these cables. The splicing and terminating methods for XLPE cable are easier to compare with other cables.
- Free from maintenance
XLPE cables can be installed at any place without making special consideration of the route profile as it doesn’t contain oil and you don’t need to maintain them like oil-filled cables.
- No need of metallic sheath
XLPE cable doesn’t require metallic sheathing. Because it is resistant to corrosion and fatigue, it doesn’t encounter failures.
Manufacturers test the cables in following ways-
- Routine tests
These are tests performed for monitoring the overall cable quality and function. Tests included in the routine tests list are high voltage tests, insulation resistance tests, conductor resistance tests, and voltage tests.
- Type tests
These tests are performed to calibrate and validate cable design type. These tests are bending tests, impulse voltage tests, thermal stability tests, corona level tests, and dielectric thermal resistance tests.
- Special tests
These tests are conducted to check major changes made to the design of the cables to proper performance thresholds.
- Post installation tests
Post installation tests are used to determine and ensure that cables installed in optimum operating conditions.
