Electrical Construction & Engineering
Maziya General Services is a premier provider of end-to-end electrical construction and engineering services, bridging the gap between traditional power infrastructure and the modern green energy transition. We specialize in the design, procurement, installation, and maintenance of electrical systems across the entire power lifecycle—from Low Voltage (LV) internal reticulation to complex Extra High Voltage (EHV) transmission infrastructure.
Our expertise spans substations, reticulation networks, renewable energy integration, and long-term asset maintenance, ensuring reliable, safe, and future-ready power solutions.
Our Core services
Substation Engineering & Infrastructure
We deliver high-stakes engineering for specialized substation environments, ensuring seamless power transformation and control.
- Transmission Substations (Up to 765kV): EPCM services for high-capacity hubs, power transformers, and EHV switchyards designed for grid stability.
- Traction Substations (3kV DC & 25kV AC): Custom construction for railway electrification, converting utility power for heavy-haul and commuter rail networks.
- Distribution Substations: MV switching stations, MV/LV hubs, ring main units (RMUs), and pole-mounted transformers for urban and industrial zones.
- Collector Substations: Facilities designed to aggregate renewable energy generation for grid feed-in.
MV & LV Reticulation Networks
We provide the vital links connecting bulk power to industrial, commercial, and residential end-users.
- MV Networks (1kV – 33kV): Overhead lines, underground cabling, trenching, and jointing.
- LV Distribution: Internal and external reticulation compliant with SANS 10142-1 safety standards.
- Miniature Substations (MSS): Localized step-down substations for efficient distribution.
- Smart Metering: AMR systems for accurate billing and load management.
Renewable Energy & Solar Integration
We offer a full-spectrum EPC model for the green energy sector.
- Utility-Scale Solar: Construction of large PV plants with EHV grid integration.
- Commercial & Industrial (C&I) Solar: Rooftop and carport solutions for energy independence.
- Battery Energy Storage Systems (BESS): Advanced storage solutions for backup power and peak-shaving.
- Compliance: Grid-Code compliance and SSEG registration expertise.
Maintenance & Emergency Support
We maximize asset lifecycle through proactive support and rapid response.
- 24/7 Emergency Repairs: Fast fault localization and restoration for LV, MV, and HV networks.
- Preventive Maintenance: Thermal imaging, oil sampling, and condition monitoring.
- Solar O&M: Specialized testing and optimization for renewable sites.
