LV & HV Installation FAQ

Have questions about our LV and HV electrical installation services? Explore our FAQ section for clear and concise answers about our processes, safety standards, certifications, and more.

What is the difference between LV and HV electrical installations?

LV (Low Voltage) installations typically deal with voltages up to 1kV, while HV (High Voltage) installations involve voltages above 1kV, often up to 33kV or more. HV installations require specialized equipment and safety protocols due to the higher voltage levels.

What does the LV & HV electrical installation process involve?

The process includes everything from site assessment, cable laying, substation installation, to final connection to the Distribution Network Operator’s (DNO) network. We handle each step with precision to ensure safety, compliance, and reliable operation.

What is the role of a secondary substation in electrical installations?

A secondary substation is used to reduce voltage levels and distribute power to local areas. It’s a key component in ensuring the safe and efficient flow of electricity from high-voltage transmission systems to lower-voltage distribution systems.

How long does it take to complete an LV or HV electrical installation?

The duration depends on the complexity of the project. For example, simpler LV installations may take a few days, while more complex HV projects could take several weeks. We provide detailed timelines during the planning stage.

What are cable jointing and termination services?

Cable jointing involves connecting two cables to form a continuous power network, while termination refers to safely connecting the ends of cables to electrical equipment or junctions. Both processes ensure the integrity and safety of the electrical system.

What are diversion works for LV and HV cables?

Diversion works are required when existing cables need to be rerouted to avoid obstructions or accommodate new developments. We manage the entire diversion process to minimize disruption and ensure compliance with safety standards.

Do you handle both installation and maintenance of LV & HV systems?

Yes, we offer both installation and maintenance services for LV and HV electrical systems. Regular maintenance ensures that systems remain reliable, safe, and efficient throughout their lifecycle.

Are your installations compliant with industry standards?

Absolutely. All our installations comply with industry standards, including NERS accreditation, ensuring that our work meets the highest safety and regulatory requirements.

What safety measures are in place for LV and HV installations?

We follow strict safety protocols, including the use of personal protective equipment (PPE), risk assessments, and adherence to regulatory safety standards to ensure the safety of both our team and your property.
