In the context of electrical cables, PVC and XLPE are two materials used as insulation. XLPE has got more capacity to hold on incase of high temperature. XLPE will not deteriorate it's insulating property until it reaches 90 degree celsius. It will not suddenly lose it's insulating property if the themperature jumps just above 90. But the overall life of the cable will be reduced. PVC can withstand temperatures only upto 70 degree Celsius.
PVC is cheaper than XPLE, hence it's find it's place in market today.
PVC is a thermo plastic where as XLPE is thermosetting plastic.
PVC - Poly Vinyl chloride
XLPE - Cross linked Poly Ethylene

What is the purpose of semiconductor over XLPE?
The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
Which kind of cable are used in hvdc transmission system?
In HVDC (High Voltage Direct Current) transmission systems, the primary types of cables used are underground cables and submarine cables. These cables are typically made from materials like cross-linked polyethylene (XLPE) or oil-filled cables, designed to withstand high voltage and environmental conditions. They are insulated to prevent electrical leakage and ensure safe transmission over long distances. Additionally, the use of bipolar cables allows for efficient transmission and improved reliability in the system.
What is the meaning of ingress in electrical?
You are probably referring to moisture ingress. Moisture ingress into underground electrical cables, particularly high-voltage cables, can act to break down the insulating properties of that cable, and lead to a short circuit. Accordingly, underground cables incorporate a sheath (lead in older cables), which is impervious to moisture ingress, which surrounds the cable cores, and is located beneath the outer armouring. But moisture ingress can occur with all types of electrical equipment, and the manufacturers take steps to prevent this from happening.
What is the difference between a sioplas line and a ccv line for manufacturing of xlpe cables?

Which plastic is used for making wire insulation?
Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.
What is the meaning of the 2xfy in cable?
Copper XLPE Armoured Power Cables.
What is xlpe resin?
XLPE (cross-linked polyethylene) resin is a type of thermosetting polymer used in the manufacturing of electrical cables. It offers high thermal and chemical resistance, excellent electrical properties, and low water absorption. XLPE resin is commonly used in medium to high voltage power cables for transmission and distribution of electricity.
What is the meaning of 2xwy in cables?
2X - XLPE insulation W - Copper conductor Y - PVC sheath
Why drop voltage in xlpe cable is more than PVC cable?
The higher voltage drop in XLPE cables compared to PVC cables is due to the different electrical properties of the materials. XLPE has a lower dielectric constant and higher resistivity than PVC, leading to a higher internal resistance and therefore higher voltage drop. Additionally, XLPE cables usually have a higher operating temperature, which can also contribute to increased voltage drop.
What is the purpose of semiconductor over XLPE?
The purpose of the semiconductor over XLPE is to equalize the electrical stresses over a large area.
What is maximum minimum temperature of submarine XLPE cables?
The maximum operating temperature for submarine XLPE cables is typically around 90 degrees Celsius, while the minimum temperature for operation would be around -15 to -20 degrees Celsius. These temperature ranges ensure that the cables can function effectively in various marine environments.
What is full form of the XLPE?
The full form of XLPE is Cross-Linked Polyethylene. XLPE is a type of polyethylene in which the polymer chains are chemically linked, or cross-linked, to improve its thermal and mechanical properties. This cross-linking enhances the material's resistance to heat, pressure, and environmental stress, making it suitable for use in insulation for high-voltage cables and wires.

What does PEX stand for?
Cross-linked polyethylene, commonly abbreviated PEX or XLPE, is a form of polyethylene with cross-links. It is formed into tubing, and is used predominantly in hydronic radiant heating systems, domestic water piping and insulation for high tension (high voltage) electrical cables.
