Accurately sizing glands for armoured cables involves a few key steps:

  • Determine the size of the armoured cable: Measure the diameter of the cable, including the outer jacket and the armour layer.
  • Determine the size of the cable gland: Use a cable gland sizing chart or calculator to determine the correct size gland for the cable. This will typically involve matching the diameter of the cable to the appropriate gland size.
  • Choose the correct type of gland: Depending on the application and environment, there may be different types of glands available (such as weatherproof, flameproof, or explosion-proof).
  • Choose the gland type that is appropriate for the specific application.
  • Consider additional factors: Depending on the specific installation, there may be additional factors to consider when sizing glands, such as the type of enclosure or fitting the gland will be attached to, or the specific requirements of the application.
  • It's important to ensure that the gland is sized correctly for the cable to ensure a secure and safe connection.

If in doubt, it may be helpful to consult with a knowledgeable professional or refer to industry standards and guidelines.

Fitting an armoured cable gland involves several steps:

  • Choose the appropriate location for the gland: Ensure that the location is suitable for the application and that the cable can be routed to the gland without excessive bends or twists.
  • Prepare the cable: Strip back the outer jacket and the armour layer of the cable to expose the conductors. The length of the exposed armour layer should be in line with the manufacturer's recommendation.
  • Prepare the gland: Check the manufacturer's instructions for any specific preparation required for the gland, such as removing any protective caps or seals.
  • Insert the cable into the gland: Thread the cable through the gland body, ensuring that the armour layer is correctly aligned with the clamping mechanism of the gland. The armour layer should be held securely by the clamping mechanism.
  • Tighten the gland: Tighten the gland body using the appropriate tool, such as a wrench or spanner. The gland should be tightened to the manufacturer's recommended torque setting.
  • Check the installation: Inspect the gland and cable to ensure that the installation is secure and that there are no visible signs of damage or misalignment.

It's essential to follow the manufacturer's instructions and any applicable industry standards and regulations when fitting an armoured cable gland to ensure a safe and secure installation. If in doubt, it may be helpful to consult with a knowledgeable professional.

 

UK Regulations Pertaining to Cable Glands

In the UK, the installation of armoured cable glands is governed by several regulations, including:

  • The Electricity at Work Regulations 1989: These regulations require that electrical systems, including cable glands, are installed, maintained, and used in a way that prevents danger.
  • The Wiring Regulations (BS 7671): These regulations provide guidance on the design, installation, and maintenance of electrical installations, including the selection and installation of cable glands.
  • The Construction (Design and Management) Regulations 2015: These regulations apply to construction projects and require that risks associated with the installation of electrical systems, including cable glands, are identified and managed.
  • The Health and Safety at Work Act 1974: This act places a general duty on employers to ensure the health and safety of their employees and others who may be affected by their work, including the installation of cable glands.
  • The Control of Substances Hazardous to Health Regulations 2002: These regulations require employers to assess and control the risks associated with hazardous substances, including those that may be present during the installation of cable glands.

It's important to consult these and any other relevant regulations when installing armoured cable glands in the UK to ensure compliance and a safe installation. Additionally, guidance from organizations such as the Health and Safety Executive (HSE) and the Institution of Engineering and Technology (IET) may be helpful in understanding and meeting regulatory requirements.
