Package Substation

substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

“High voltage/low voltage preassembly transformer house” defined by national standard and “box-type transformer house” for short call is composed of high voltage switchgear, power transformer and low voltage switchgear. It is better than civil designs for its advantages like flexible and convenient usage, small volume and floor space, low cost, fast construction, high reliability so on. It is widely used in reform of the city network, high buildings, residences, industrial areas, business centre, airports, stations and ports, schools and industrial and mining enterprises and other occasions.

Sun Shine has manufactured a number of Package Substations for different projects. Low cost, Ease of installation, operation and maintenance, different colors options are few benefits.


  1. The frame of the substation is made with Steel or Alu of relative high mechanical strength and is welded. The transformer house is composed of high voltage room, transformer room and low voltage room.
  2. Doors are made of steel or A-alloy, which passes anti-corrosive treatment and can be used outside for a long-period.
  3. There are independent small cubicles in the substation and they can be removed for easy access of maintenance.
  4. The top can be of two layers to prevent heat radiation and can serve for both natural and forced ventilation to meet energy saving requirement.
  5. Transformer cubicle has a safety net door. The door and the main switch of high voltage part serve dual safety purpose of preventing mistakenly stepping into charge clearance. Client can select different structural style according to their needs.
  6. Provision for putting Lighting devices to be installed in various cubicles and are controlled by the doors.


  • Compact construction, High Strength, Small floor space- One fifth of that of the civil design transformer station.
  • Low cost: Lower investment than that of the civil design transformer station
  • Easy and convenient installation: The operation men on site only need to fasten installation screws and connect the inlet/outlet cables and the earth lines.
  • Safe and reliable: Totally-enclosed design, completely insulating structure with protection degree ≥ IP33.
  • Easy and convenient maintenance
