YB Prefabricated Substation

Compact structure; strong nature of complete set; reliable operation; easy maintenance; beautiful appearance. Preferred complete set for urban and rural power distribution.

Type Meaning (Model Code)

YB – □ / □ – □

YB: Prefabricated substation
□: Structure type (M for compact)
□: High voltage side voltage (kV)
□: Low voltage side voltage (kV)
□: Rated capacity (kVA)

Example: YB-M-10/0.4-100 means Prefabricated substation, Compact type, 10kV high voltage, 0.4kV low voltage, 100kVA capacity.

Product Overview

Combined substation: complete equipment assembly and passed type-tested. Main components: transformers, high-voltage switchgear and control equipment, low-voltage switchgear and control equipment, the corresponding internal wiring (cables, bus bars and other), and auxiliary equipment. Combined substation can be operated inside or outside through the cable. It can be (in part or in whole) mounted on the ground or under the ground.

The products are the series products self-designed by the Company based on ZGS combined transformers to meet the needs of urban and rural power grid construction. With a small size, compact structure, and short-term of on-site installation and commissioning, it can replace the traditional substation (station). It can also meet configuration requirements of various programs such as the user power metering, reactive power compensation, high and low voltage, representing the development direction of small and medium-sized substations (stations).

This product is suitable for industrial and mining enterprises, station, wharf, airports, public places, high-rise buildings and 10kV, 50Hz, 30~1600kVA power users in residential areas, applying for not only power supply network but also for terminal.
