Product Details

Schneider Authorized Modular Manufacturing.

Complete set, compact structure, safe and reliable operation.

Beautiful shape, fast installation and convenient construction.

Easy to operate, high reliability.

Product structure and shape:


It consists of high-voltage switchgear, power transformer, and low-voltage switchgear.

Strong package, small footprint, low investment, convenient installation and maintenance.

Beautiful shape, highlighting green and environmental protection concepts.

Welding of profiled steel with good mechanical strength.

Good surface treatment and strong weather resistance.

Appearance of abundant materials and colors, a wide range of user choices.

The internal structure has "mesh" type and "product" type, and there are "corridor type" and "no corridor type".

Product structure:

    The product is a frame structure, which is welded with steel or assembled from steel plates. The frame is covered with a special paint layer, which has strong mechanical properties, weather resistance and corrosion resistance. When the prefabricated (box type) substation has an overall structure, the inside of the box is divided into three relatively independent small rooms, namely a high voltage room, a transformer room and a low greenhouse. The lighting of each room is automatically turned on and off as the door is opened and closed. Pre-installed (box type) substations have a heat insulation layer on the top to prevent condensation from occurring due to rapid changes in the temperature in the high temperature and cold regions, and a mating layer can be installed around the box. In order to stabilize the temperature in the box, the transformer room and low-voltage room are equipped with automatic temperature control devices.

Box body:

High pressure chamber

    A high-voltage ring network cabinet is installed in the high-voltage room, which has perfect "five defenses" function. High-voltage switch can choose sulfur hexafluoride load switch and vacuum circuit breaker. The high voltage cabinet has a variety of protection functions such as short circuit and overload to the transformer.

Transformer room

    The transformer room is equipped with a dry or liquid (oil) immersed transformer. The cabinet is equipped with a perfect ventilation system, and the temperature control value can be set according to needs. The transformer is provided with a mistakenly-charged interval device to prevent it from being mistakenly observed.

Low pressure room

    Low-voltage room is divided into two types of assembly with and without corridor. Metering cabinets, main incoming cabinets, outgoing cabinets, capacitor cabinets, and contact cabinets (when two transformers) can be installed indoors, with the overall function of low-voltage complete switchgear. The general measuring cabinet and the main switch are integrated, that is, the upper part of the cabinet is the instrument, the measuring box, and the middle and lower parts are automatic air switches, lightning arresters, and transformers. The capacitor cabinet can be manually or automatically controlled for automatic compensation. Capacitor reactive power compensation capacity is generally 15-30% of the transformer capacity.
