ZGS11-12/0.4 Prefabricated Substation Product Introduction

1. Product Overview

The ZGS11-12/0.4 prefabricated substation is a compact American-type box-type substation independently developed and manufactured for 12kV urban and rural power distribution systems. It integrates high-voltage switchgear, oil-immersed distribution transformer, low-voltage power distribution unit, protection device and auxiliary electrical components into a fully sealed box structure, realizing an all-in-one solution for power transformation, distribution, metering and protection.

Different from traditional on-site assembled substations, this product is fully prefabricated, wired and tested in the factory. It only requires foundation fixing and external cable connection after delivery to the site, which greatly shortens project construction cycle. Adopting mature ZGS11 series energy-saving transformer core technology, the equipment features low loss, low noise and stable operation, fully complying with GB17467 and DL/T537 national and industry standards, and is widely applicable to various outdoor and indoor power supply scenarios.

2. Main Product Parameters

The ZGS11-12/0.4 prefabricated substation supports multiple capacity specifications to meet different power demand scenarios. The core technical parameters are standardized and calibrated, with stable and reliable indexes as follows:

3. Product Core Features

3.1 Compact and Integrated Structure

The whole equipment adopts an integrated modular design, which saves more than 60% of installation space compared with traditional separate substations. All live parts are fully sealed and insulated inside the box, with no exposed charged components. The overall layout is reasonable and compact, adapting to narrow installation spaces such as urban green belts and roadside corners without occupying excessive construction land.

3.2 Energy-saving and Low-consumption Operation

Equipped with ZGS11 series high-efficiency energy-saving transformer core, the product effectively reduces no-load loss and load loss during long-term operation. The optimized electromagnetic structure design lowers operating noise to below 55dB, realizing low-noise and energy-saving power supply. It can effectively reduce long-term operating power consumption costs for users and meet national energy-saving and emission-reduction requirements.

3.3 Comprehensive Safety Protection

The equipment is equipped with double-sided high-voltage fuse protection and low-voltage undervoltage and overcurrent protection systems, with full-range fault protection functions. The fully sealed metal box body has good rainproof, dustproof, anti-corrosion and anti-theft performance, adapting to harsh outdoor environments. The zero-potential terminal surface design ensures construction and maintenance personnel safety during daily operation.

3.4 Flexible and Convenient Installation

All internal wiring, debugging and performance tests are completed in the factory. On-site construction only needs simple foundation treatment and cable access connection, which greatly reduces on-site construction difficulty and shortens the project delivery cycle. It supports ring network power supply, dual power supply and terminal power supply modes, with flexible configuration to adapt to different grid connection schemes.

3.5 Strong Environmental Adaptability

The box body adopts anti-corrosion spray treatment, which can resist wind, rain, frost and ultraviolet erosion. It can operate stably in high temperature, low temperature and humid environments, with strong environmental adaptability and long service life, basically free from frequent environmental impact failures.

4. Application Scenarios

Thanks to its compact size, safe operation and convenient installation, the ZGS11-12/0.4 prefabricated substation covers most civil and industrial power supply scenarios, and is the preferred equipment for urban and rural power grid upgrading and new power distribution projects:

• Urban and Rural Power Grid Renovation: Used for old community power grid upgrading, rural power grid reconstruction and regional power distribution optimization, solving the problems of insufficient power supply and aging equipment in old areas.

• Residential and Commercial Supporting: Suitable for residential communities, shopping malls, office buildings, hotels and other commercial and residential areas, providing stable and continuous power supply for daily life and commercial operation.

• Industrial Production Sites: Applicable for factory workshops, mining enterprises, industrial parks and other industrial scenarios, meeting the high-load and stable power demand of industrial production equipment.

• Public Infrastructure: Matched with schools, hospitals, scenic spots, parks and other public facilities, realizing safe and reliable public power guarantee.

• Transportation Hubs: Used for power supply support of highways, railway stations, airports and other transportation facilities, adapting to outdoor unattended operation conditions.

• Temporary Engineering Power Supply: Suitable for construction sites, temporary activity venues and other temporary power consumption scenarios, with convenient installation and flexible movement.

5. Product Maintenance and After-sales Service

5.1 Daily Maintenance Guidelines

The ZGS11-12/0.4 prefabricated substation is designed with low maintenance performance, and daily maintenance is simple and operable for on-site personnel. It is recommended to carry out regular inspection and maintenance according to the following specifications to ensure long-term stable operation:

• Monthly Routine Inspection: Check whether the box body is damaged or deformed, whether the sealing parts are aging or leaking oil, confirm that the indicator lights and instrument data are normal, and clean the dust on the box surface and ventilation holes.

• Quarterly Functional Inspection: Test the sensitivity of high and low voltage protection devices, check the tightness of cable joints and wiring terminals, and eliminate hidden dangers of loose wiring and poor contact.

• Annual Comprehensive Maintenance: Conduct oil quality detection of transformer oil, inspect internal insulation performance and component aging degree, clean internal dust and dirt, and calibrate metering and protection parameters to ensure equipment performance meets standard requirements.

• Environment Adaptation Maintenance: Strengthen inspection in rainy season, high temperature and winter low temperature seasons, check waterproof and heat dissipation, anti-freezing performance, and avoid equipment failure caused by extreme weather.
