Installation and Maintenance of 70mm Armoured Cable

Installation and Maintenance of 70mm Armoured Cable

Earth for the Cable

The first and foremost step in the installation process of an armoured cable is to ensure proper earthing. Earthing is essential for the safety of both equipment and personnel. A conductor must provide a low impedance path to the earth, thereby diverting any fault current into the ground. The cable should be installed in a trench with the appropriate earth bar at intervals to ensure proper grounding. The earth cable should also be of the same size as the power cable.

Cable Bedding and Sheath

Once the earthing is done, the cable should be bedded in a layer of approved bedding material that provides a protective cushion and helps in distributing the load evenly. This will also help in soaking moisture from the ground and avoiding any damage to the cable. After the bedding, the cable should be secured with a sheath that provides an extra layer of protection against mechanical damages, weathering, and UV degradation. The sheath should be made of materials that are resistant to chemicals and corrosion and should have a high impact strength.

Glands and Cleats

Glands and cleats play a vital role in securing the connection between different components of an armoured cable. Glands are mechanical cable fittings that create a seal between the cable and equipment or enclosure. The cable should be fed through the gland, which should then be tightened properly to ensure a secure connection with the equipment. Cleats, on the other hand, are designed to hold the cable tightly in place and prevent it from moving under stress. The type and size of glands and cleats should be selected based on the cable size and application requirements.

Protective Measures

Protective measures are necessary for securing the cable from any damage and preventing any accidents from occurring. This can be done by installing barriers, signs, and enclosures that provide protection from vehicles and other construction equipment. It’s also important to take into account the temperature, humidity, and other environmental factors that can affect the cable’s performance and longevity. Regular maintenance and inspections should also be carried out to ensure the armoured cable is in good working condition.

Fast Delivery and Additional Information

Finally, when it comes to fast delivery of the armoured cable, it’s important to select a trusted supplier that can provide a reliable and efficient service. The supplier should have a track record of timely delivery, good quality products, and excellent customer service. Additionally, it’s important to have access to additional information, such as product datasheets, technical specifications, and user manuals, to help you make informed decisions about the product and its usage.
