Because of the following benefits we use cross linked polyethylene as insulation for cables.
1) Works with a variety of voltage ranges 600 V to 35 kV
2) Provides mechanical protection
3) Can withstand extreme pressure
4) Resists underground damage
5) Weather resistant
6) Thermal resistant
7) Permits high conductor operating temperatures
8) Reduces short circuit and overload levels
8) Moisture resistant

Insulation for Cables in Low Voltage to 33 kV Range
Insulation is an essential part of cables and wires used in electrical systems. It provides a barrier between the conductor and the surroundings, preventing any leakage of current or voltage. The most commonly used insulation for cables in the low voltage to 33 kV range is Vulcanised India rubber.
Properties of Vulcanised India Rubber Insulation
Vulcanised India rubber has several properties that make it an ideal choice for cable insulation. Some of these properties include:
1. Good Dielectric Strength: Vulcanised India rubber has excellent dielectric strength, which means it can resist electrical breakdown even under high voltage conditions.
2. High Insulation Resistance: The insulation resistance of vulcanised India rubber is quite high, which ensures that the current leakage is minimal.
3. Good Thermal Stability: Vulcanised India rubber can withstand high temperatures and has good thermal stability, which makes it suitable for use in various environmental conditions.
4. Resistance to Chemicals: Vulcanised India rubber is resistant to various chemicals, including oils and acids, which makes it ideal for use in harsh environments.
5. Flexibility: Vulcanised India rubber is flexible and can be easily molded into different shapes, making it ideal for use in cables and wires.
Conclusion
In conclusion, Vulcanised India rubber is the most commonly used insulation for cables in the low voltage to 33 kV range. It has several properties that make it an ideal choice for cable insulation, including good dielectric strength, high insulation resistance, good thermal stability, resistance to chemicals, and flexibility.
