Zgs11 Three Phase Pad-Mounted Transformer Substation Compact American Box Type Power Supply Electrical Substation China Factory Price 10kv

A pad-mounted substation is an electrical power distribution system that is typically installed at ground level, enclosed in a weatherproof and secure steel cabinet. It's commonly used in residential, commercial, and industrial areas where space is limited or overhead lines are not feasible. In addition to the transformer, a pad-mounted substation can have medium-voltage switchgear or switchboards for disconnecting and redirecting power flows, protective relays to monitor and protect the system from faults, and potentially even a secondary transformer if multiple voltage levels are required.

Qinghao pad mounted substation feature a tamper resistant construction with no externally accessible bolts, hinges, screws or fasteners, thus providing a safe, self-contained unit which cannot be accessed by unauthorized personnel. Unsightly fences or other forms of protective devices are not necessary. Completely factory assembled, the units are shipped in one piece.

Enhanced safety, Ease of Maintenance and Accessibility, Space Efficiency, Flexibility in Placement

Main Characteristics
1. Full insulation, fully sealed structure to guarantee the personal safety.
2. HV side adopts double fuse protection, in which the plug type fuse is the unika fuse(temperature, current), the backup fuse is the current limit fuse reducing the operating costs.
3. HV incoming line adopts cable connector structure, all insulated, safe and reliable easy to operate.
4. The transformer can be used in Ring Main Unit and terminal system with quite convenient transformation, improving the reliability of power supply.
5. The structures for transformer are three-phase three-limb or three-phase five-limb. The core uses step-lap technologies which lowers the noise and loss, and improves the short circuit withstand ability and overload ability.
6. Use special technology of vacuum drying and vacuum oil filling which used in 35kV transformer and be extended to 10kV transformers. It offers a strong guarantee for quality improvement.
7. The enclosure adopts antiseptic design and special spray painting as per the service condition. The enclosure is equipped with ""three-anti"" functions: anti-condensation, anti-salt fog and anti-mildew, which can meet the anti-corrosive requirement in high temperature and high humidity condition.

Advantages
1. Compact structure, beautiful appearance, small size.
2. Flexible, safe.
3. Easy to operate and free maintenance.

Applications
1. Urban power network residential area.
2. High-rise building.
3. Industrial park, airport, station, school, especially for urban grid transformation. 

Service Environment
1. Ambient temperature: Maximum +40ºC, Minimum -25ºC
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)

Main Components:

1. Transformer: Responsible for voltage stepping down or stepping up.
2. High-Voltage (HV) Switchgear: It manages and protects the high-voltage incoming power supply, including circuit breakers, switches, and protective relays.
3. Low-Voltage (LV) Switchgear: Similar to the HV switchgear but operates at the transformed, lower voltage level. 
4. Fuses and/or Circuit Breakers: These provide overcurrent protection, preventing damage to equipment during abnormal current conditions. 
5. Metering and Monitoring Equipment: To measure and monitor the electricity consumption, quality, and status of the substation, various meters, sensors, and communication devices may be installed. 
6. Grounding System: A critical safety feature, which includes grounding conductors, rods, and plates.
7. Enclosure/Cabinet: The entire assembly is housed in a robust, weather-resistant, and lockable steel cabinet.
8. Cables and Connectors: High- and low-voltage cables connect the substation to the primary power source and distribute power to the local network. 
9. Busbars: These conductive bars or strips within the switchgear facilitate the distribution of electrical power between different components.
