ConstructionHV & LV Distribution

HV & LV Power Distribution

The backbone of every large building. We design and install complete high-voltage and low-voltage distribution systems from network connection point to final sub-circuit — compliant, commissioned and handed over on programme.

Overview

High-voltage and low-voltage power distribution is the foundation of every large electrical installation. From the point of supply at the network boundary through to the final distribution boards serving each tenancy and building service, the design and installation of the distribution system determines the reliability, efficiency and compliance of everything that follows.

Reprise Electrical delivers complete HV/LV distribution packages on major commercial and infrastructure projects. Our capability spans HV cable installation and jointing, ring main units, padmount transformers, switchrooms, and LV main cable reticulation — all executed to AS/NZS 3000 and the specific requirements of the local network authority.

We coordinate closely with network authorities, structural engineers and head contractors throughout design and installation, managing energisation approvals and commissioning hold points to keep the project on programme.
