What causes underground cable damage?

While excavating machines are commonly responsible for cable damage, workers are also exposed to danger when they use hand tools such as pneumatic drills, crowbars, picks and forks to dig around underground cables.

This makes it important to contact a professional service provider to install new or repair damaged cables. If you are experiencing any type of issue or damage with your underground service and consumer mains, it’s best to call one of our Level 2 electricians, as we have the expertise to safely work with underground electricity.

Enhanced Aesthetics
Underground electric cable eliminates the need for overhead power lines, resulting in a cleaner and more visually appealing environment. It removes unsightly poles and cables, enhancing the aesthetics of your property and contributing to an unobstructed view.
Increased Safety
Underground electricity significantly reduces the risk of accidents and injuries associated with overhead power lines. By eliminating the exposure to live wires, it enhances the safety of your home and reduces the chances of incidents caused by factors such as falling branches, severe weather, or accidental contact.
Reliable Power Supply
Underground electricity provides a more reliable power supply, as it is less susceptible to external factors like storms, strong winds, or wildlife interference. The buried cables are better protected against environmental elements, resulting in fewer disruptions and power outages, ensuring a stable electrical service.
Reduced Maintenance
Underground electricity requires minimal maintenance compared to overhead power lines. With no exposure to the elements, the cables are less prone to wear and tear, reducing the need for frequent inspections and repairs. This translates to long-term cost savings and fewer disruptions to your daily activities.
Installing underground electricity future-proofs your property by accommodating the increasing demand for electrical power. It allows for future expansions, such as adding additional circuits, installing electric vehicle chargers, or integrating new technologies, without the limitations or aesthetic concerns of overhead lines.

Consultation with a qualified electrician is recommended to assess the feasibility and requirements for converting to underground electricity.
Are there any specific considerations for maintenance and repairs of underground electrical systems?

Have to say it's rare to come across any companies such as selectrical services these days. Their custom service is excellent and backed with prompt service. They would text you to inform when their electrician would arrive. When they promise something, they would keep their promise. We had really good experience having them to carry out electrical work.
