The process of armouring a cable is done by amalgamating several electrical conductors together. In most occasions, two conductors are joined together. This specific electrical cable, steel wire armoured cable, is a power cable designed for the provision of public electrical power.
Lately, most services including telecommunication services have been running their cables underground, which is a safer means of transit for their data. Electrical companies have also been in the loop by running underground cables. The steel wire armoured cable is the most suitable power cable for underground power network.
Underground power cable networks are used in areas where it is not possible to install overhead cabling systems. For instance, it is wise to use underground cabling in areas where there are factories and densely populated urban areas. Also, the underground cabling can be used to connect households from the main line overhead cable networks. In Singapore, most cable networks are built underground.
Underground cabling has the following advantages when compared to overhead cabling:
- It has minimal voltage drops.
- The cost of maintenance is lower as compared to overhead cabling.
- It has minimal faults.
The steel wire armoured cable is the kind of power cable that is made for the integration of an underground power network.
Structure of the underground steel wire armoured cable
The structural design of this armoured cable enhances the ability of the cable to perform as required. The following are parts of this power cable:
- The cable is made of a conductor. The conductor used in this cable is copper. Copper is widely used as a means of electrical current flow.
- An insulating material is used in the making of this cable. The most suitable being polyethylene, which is useful for its resistivity of water.
- The cable is then bedded using a PVC material. The purpose of this material is to create a divisional line between the internal and external cable parts.
- The cable can be rolled without breaking due to the pliability of the steel.
- The final layer of the cable is a sheath whose main purpose is to hold the interior constituents of the cable. Also, it protects the inner parts of the cable.
Benefits of a Steel Wire Armoured Cable
The steel wire cable offers the following benefits when implemented:
- Its structural design provides suitability for underground power network cabling. It is one of the best cables to be used for underground electrical power.
- It is well protected for complex wiring networks.
- It provides earthing to whatever it is connected to.
The Steel Wire Armoured power cable is a solution to complex electrical networks that run underground. To find out more specifications of this wire, contact a cable supplier in Singapore and find out how the steel wire armoured cable can answer to your needs.
