11kv Pad Mounted Transformer Plug in Cable Switchgear American Type Power Transformer

11KV Pad Mounted Transformer Economic type with plug in cable switchgear American type power transformer
Products Advantage:

• 1.Compact structure, small volume, is only about the 1/3 - 1/5 of the same capacity european type substation, which greatly reduce the occupation area
  2.Fully sealed and fully insulated structure, no need insulation distance .
  3.The wiring connection of high voltage can be used in loop feed and radial feed. Power supply method is flexible and reliable.
  4.Excellent performance; low consumption, low noise, low temperature -rising, high overload, anti short-circuit, high impact resistance, reliable protection of personal safety
  5.Meet all kinds of low voltage outgoing requirements .
  6.Cable head has 200A elbow plug & 630A "T" shape fixed type. All insulated Zinc Oxide lightning arrester can be configured. 200A cable head can be plugged in with load, also can be acted as isolation switch.

  Technical Parameter

Structure Characteristics

• The enclosure structure is made of channel steel and angle steel which has higher mechanical strength. The enclosure is made of aluminum alloy plate ,its face is even and smooth . The product is elegant appearance with better anti-erosion. The foundation of substation is higher 300- 600 mm than ground. All the doors are opened outward with angle more than 90°. The substation has handle, dark latch and dormant lock with waterproof anti-blocking and anti rust.

•  

• The body is whole enclosed against theft to ensure the working under a common air temperature, the temperature of all electrical devices do not be more than the max. allowed temperature of itself. It is equipped with enough natural vents and insulation measures.The prefabricated transformer substation is equipped with special grounding conductor .On the grounding conductor ,there has terminals to connect with ground net .Its number is more than two pieces and has obvious grounding mark. The ground terminal is copper bolt with diameter more than 12mm. The grounding conductor adopts copper strip which current density can not be more than 200A/mm, the cross section is more than 30mm , to ensure that the flow through the maximum short-circuit current does not overheat or affect the safety of the surrounding objects. Dynamic and thermal steady current of the special grounding conductor should be equipped with grounding methods of H.V. power distribution devices.
