Cable joint Types and Customs Codes in the UK
Cable glands are key components in power systems and are used to provide reliable and safe connections between power cables. In the UK, cable glands are widely used in utilities, industry and commercial sectors. Understanding the types, sizes and international customs classifications of cable glands is essential for importers, exporters and engineers.
UK Cable Gland Types
Cable glands in the UK are usually classified according to voltage level and installation method.
• Low Voltage (LV) Cable Gland (up to 1KV)
Commonly used in home and commercial networks, including heat shrink, cold shrink and resin types.
• Medium Voltage (MV) Cable Gland (1KV-36KV)
Used in industrial and utility applications, these glands usually use heat shrink or preformed slip-on technology.
• High Voltage Cable Gland (above 36KV)
These are dedicated products for high voltage transmission systems and are usually customized and tested to specific standards.
• Heat Shrink Gland
Made of heat shrink tubing, it seals and insulates the connection. Widely used in low and medium voltage applications.
• Cold Shrink Fittings
Pre-expanded silicone rubber tubing that shrinks into place without the need for heat. Ideal for locations with limited access and environments susceptible to moisture.
• Resin Cast Fittings
Filled with a two-component resin compound, providing strong mechanical and moisture protection. Ideal for underground installation.
Sizes and Specifications for UK Cable Gland
The size of cable fittings in the UK is generally defined by the cable core size (cross-sectional area in mm²), the number of cores and the applicable voltage level. Some common examples include:
• Single core 25mm2 low voltage fitting.
• Three core 95mm2 low voltage heat shrink fitting.
• Three core 185mm2 medium voltage cold shrink fitting.
• Single core 630mm2 high voltage fitting.
Standards such as BS7888, BS EN50393 and IEC 60502 may govern their design and testing.
HS Codes (Customs Codes) for UK Cable Glands
In the international trade of cable fittings, Harmonized System (HS) codes are used to classify goods for customs clearance and tax purposes. In the UK and many countries, cable glands are often classified as:
• HS Code: 8547.20
Plastic insulating fittings for motors, appliances or apparatus. This category includes connectors, sleeves and similar articles used in wiring systems.
Other product details or material composition (such as resin content or metal parts) may slightly affect the classification. It is recommended to confirm the final HS code with the customs broker or refer to the UK trade tariff.
