Suspended Substation – K320

Suspended Substation – K320 installed outdoors on sturdy mounting frames, creating a stable electrical grid. The substation provides and stabilizes the main power supply for the system. Engineers will fabricate and support the transformer and electrical equipment using a strong tower foundation system, making this product ideal for use in factories, industrial zones, and particularly in rural areas or locations with challenging terrain.

Construction of the Suspended Substation – K320

There are currently various types of suspended substations with different power capacities. The basic structure of this type includes the following components:

Transformer

• Typically, a 3-phase transformer is used, or three 1-phase transformers
• The transformer capacity can reach up to 630 KVA.

Medium Voltage Switchgear and Protection Equipment

• Includes: Disconnecting switch or load break switch, lightning arrester, and drop-out fuse.
• Disconnecting Switch: Plays a role in switching the medium voltage power on and off to the substation.
• Lightning Arrester: Protects the substation from lightning surge currents on the power lines.
• Drop-out Fuse: Protects the substation from overloads in the circuit.

Low Voltage

• The low voltage cabinet is equipped with circuit breakers according to the transformer’s capacity
• Capacitor banks are installed to reduce power losses and save costs

Substation Tower Foundation

• This is the area where two tower poles of the transformer substation are anchored
• The foundation is made of solid concrete, capable of supporting the entire substation and transformer
• The tower structure must be cast and poured according to strict standards, typically reaching a height of up to 12 meters

Galvanized Crossbeam System

• This system serves to support the transformer and the switchgear and protection devices of the substation
• It is typically fabricated from iron, steel, or sheet metal, then galvanized through hot-dip galvanizing to prevent oxidation

Advantages of the Suspended Substation

1. Space-saving: Since it is installed on poles or suspended frames, the suspended substation does not take up much ground area
2. Low cost: The installation of a suspended substation is usually more cost-effective compared to box-type substations or kiosk-style substations, as it eliminates the need for foundation construction and protective structures
3. Suitable for harsh, difficult terrain: The suspended substation can be installed in areas with complex terrain, where building a ground-level substation would be difficult or costly

Technical Specifications

• Materials: Iron, steel, sheet metal
• Surface: Hot-dip galvanized
• Rated Voltage: 22 kV
• Power Capacity: 320 KVA – 630 KVA
