OUR SPECIALIZATIONS

Our Core Medium Voltage Services

Volt Pacific Engineering focuses exclusively on medium voltage power systems, delivering technically robust, utility-approved solutions that form the critical interface between the grid and your facility. We support new installations, upgrades and long-term operation of 11kV and 33kV systems.

Medium Voltage Switchgear Systems

Installation, integration, testing and commissioning of indoor and outdoor metal-clad switchgear systems designed for safe power control, protection and isolation. Our scope includes panel erection and alignment, control and protection schemes, relay configuration, interlocking, control cabling and functional testing to ensure energisation readiness.

Power Transformer Installation & Integration

Expert installation and commissioning of oil-filled and dry-type transformers for industrial and utility-interfaced substations. We handle transformer positioning and alignment, HV and LV cable terminations, neutral grounding and earthing, oil testing where applicable, and pre-commissioning inspections in line with manufacturer recommendations and utility approvals.

HT Cable Laying, Jointing & Terminations

Complete high-tension cabling solutions covering underground cable laying, trenching and ducting, jointing, terminations and protection. All works include detailed routing documentation, insulation resistance tests and integrity checks to ensure long-term reliability and electrical safety.

Earthing & Lightning Protection Systems

Design and installation of compliant earthing and lightning protection systems that safeguard personnel and critical equipment. We execute substation earthing grids, equipment and structure earthing, transformer and switchgear earthing, lightning arresters, surge protection, earth resistance measurement and full verification documentation.

Testing & Commissioning of MV Systems

Comprehensive testing and commissioning services prior to energisation, including insulation resistance testing, relay testing, phase sequence and polarity checks, interlock and tripping verification, functional tests on switchgear and coordination with utilities for final energisation. All activities are carried out under strict permit-to-work and safety protocols.

Operation & Maintenance (O&M) Services

Lifecycle support for medium voltage assets, including preventive maintenance programs, periodic inspections, thermal imaging, relay and protection testing, emergency breakdown response and Annual Maintenance Contracts (AMC). Our O&M services are designed to maximise uptime, extend asset life and maintain compliance.
