Components

1. High Voltage CompartmentEquipped with high voltage ring main switchgear, surge arresters, voltage transformers and other high-voltage protection components for incoming circuit control and lightning protection.

2. Transformer CompartmentInstall oil-immersed transformer or dry type transformer, which realizes the step-down conversion of medium-high voltage electric energy to low voltage.

3. Low Voltage CompartmentArranged with low voltage switch cabinets, low voltage insulated busbars, electric energy metering devices and reactive power compensation equipment to complete terminal power distribution and power factor optimization.

4. Outer EnclosureMainly fabricated with high-strength steel plates or composite boards. It integrates moisture-proof, anti-rust, dust-proof, fire-resistant and anti-theft functions to fully protect internal electrical equipment.

Features and Advantages

1. Highly Integrated & Compact LayoutMultiple functional electrical devices are integrated inside one whole enclosure, effectively saving land occupation compared with traditional brick-built substations.

2. Fast On-site InstallationAll units are fully assembled and tested in factory, convenient for overall transportation and quick on-site wiring, greatly shortening project construction period.

3. Safe & Stable OperationTotally closed independent compartment structure lowers equipment failure probability and effectively avoids hidden dangers caused by external environmental interference.

4. Eco-friendly PerformanceThe whole set of equipment generates low operation noise and weak electromagnetic radiation, friendly to surrounding living and working environment.

5. Flexible & MovableSupport integral moving and relocation, perfectly matching temporary power supply demands of construction sites and temporary engineering projects.

6. Wide Application ScopeSuitable for urban power grid reconstruction, industrial park power distribution, photovoltaic and wind power new energy stations and other various power supply scenarios.
