Semi-conductive layer and insulation layer of heat shrinkable compound tube

A heat shrinkable compound tube is a type of tubing that is designed to shrink in diameter when heated. It is made of a material that reacts to heat and contracts, providing a tight seal around whatever it is wrapped around. This type of tubing is commonly used in electrical applications to insulate and protect wires and cables.

Heat shrinkable compound tubes are available in a range of sizes and can be made from various materials, including polyolefin, fluoropolymer, and elastomer. They are often color-coded to help with identification and come with different shrink ratios, which determine how much the tubing will shrink when heated.

Overall, heat shrinkable compound tubes are a versatile and effective solution for protecting, insulating, and securing wires and cables.

The semi-conductive layer and the insulation layer are two important components of a heat shrinkable compound tube.

The semi-conductive layer is typically made of carbon-filled polymer that provides an even distribution of electric stress within the insulation layer. This layer helps to prevent corona discharge, which is a phenomenon that can occur at high voltages due to the ionization of air molecules. Corona discharge is undesirable because it can degrade the insulation layer and lead to premature failure of the wire or cable.

The insulation layer is the main component of the heat shrinkable compound tube and is responsible for providing electrical insulation and mechanical protection for the wires or cables it covers. The insulation layer is typically made of a polymeric material, such as polyolefin, that has good insulating properties.

The thickness of the insulation layer is an important factor in determining the overall electrical properties and mechanical strength of the heat shrinkable compound tube. Thicker insulation layers typically provide better insulation properties, while thinner layers are more flexible and easier to install.

Both the semi-conductive layer and the insulation layer are important for ensuring the safe and reliable operation of electrical systems.
