Materials Used in Medium Voltage Cable Heat Shrink Straight Joint:

Heat Shrinkable Tubing: This is the main component of the joint, providing insulation and sealing. It's typically made from cross-linked polyolefin or similar materials.

Stress Control Tubes or Components: These components are designed to distribute electrical stress evenly and prevent corona discharge at the joint.

Mastic: Mastic is a viscous sealing material that enhances moisture resistance and provides additional insulation. It's often used in conjunction with stress control components.

Insulating Tape: Insulating tape may be used to provide additional protection and sealing over the joint area.

Typical Technical Data Associated with Medium Voltage Cable Heat Shrink Straight Joint:

Voltage Rating: Specifies the range of voltages that the joint is designed to handle, usually expressed in kilovolts (kV). Common voltage ratings for medium voltage joints might be 5 kV, 15 kV, or 25 kV.

Temperature Range: Indicates the operating temperature range that the joint can withstand without degradation of its electrical or mechanical properties.

Shrink Ratio: Specifies how much the heat shrink tubing will shrink when heated. For example, a shrink ratio of 3:1 means the tubing will shrink to one-third of its original size.

Dielectric Strength: This refers to the maximum electric field that the insulation material can withstand without breaking down. It's typically measured in volts per unit thickness (e.g., kV/mm).

Tensile Strength: Indicates how much force the joint can withstand before breaking. Expressed in pounds per square inch (psi) or Newtons per square millimeter (N/mm²).

Elongation at Break: Measures how much the joint can stretch before breaking, expressed as a percentage.

Water Absorption: The amount of water the joint material can absorb over time, which can affect its insulating properties.

Flame Retardancy: Some joints may be designed to have flame-retardant properties to enhance safety.
