Advantages of Pole Mounted Transformer

Reduced injury risks:
Residents are less likely to be injured by pole-mounted transformers. Pole-mounted transformers are kept out of reach from children and are isolated from many potential igniting sources.
Increased supply:
Pole-mounted transformer offer increased power supply, as they achieve easier distribution through the installation of necessary power lines.
Space saving:
Pole-mounted transformers are small and do not take up valuable ground space.

Types of Pole-Mounted Transformers
Conventional:
Pole-mounted transformers consisting of two sets of primary bushings are usually called “conventional type”, which mainly consist of the body part, oil tank, high and low voltage bushings, eyebolts, connection terminals, grounding devices, hooks, support ears, etc.
CSP:
CSP is a transformer with multiple protection devices such as lightning arresters, fuses, circuit breakers, etc., which can achieve complete self-protection to avoid current faults caused by its own faults under the influence of lightning, short circuits, etc. Ensure the safety of distribution lines.

Components Of Pole Mounted Transformer
Core and windings: The core is made of laminated silicon steel to minimize energy losses where the windings are typically made of copper or aluminum and are insulated to withstand high voltages.
Tank: The transformer tank is a robust enclosure that protects the internal components, and is usually made of steel and coated to resist corrosion.
Cooling system: Pole-mounted transformers use oil or air as a cooling medium to dissipate heat generated during operation. The oil also provides electrical insulation for the internal components.
Bushings: These are insulating devices that allow electrical connections to pass through the transformer’s tank safely.
Surge arresters: These are installed to protect the transformer from voltage spikes caused by lightning or switching surges.
Mounting brackets: These allow the transformer to be securely mounted on poles.
Fuses: Fuses provide protection against overcurrent and short circuits, ensuring safe operation.
Applications of Pole Mounted Transformer
Residential areas:
These transformers deliver electricity to households by stepping down the voltage to safe levels.
01
Rural electrification:
Due to their cost-effectiveness and ease of installation, pole-mounted transformers are ideal for rural areas with dispersed populations.
02
Commercial establishments:
They supply power to small businesses, shops, and offices.
03
Industrial sites:
Pole-mounted distribution transformers provide power to small-scale industries that do not require high voltage.
04
Street lighting:
These transformers are also used to power streetlights in urban and rural areas.
05

The pole-mounted transformer should be installed as close to the load center as possible to reduce the line power loss and line voltage drop of the low-voltage power supply line. Installing in complex poles such as corner poles and branch poles should be avoided.
It is recommended to keep the transformer profile at least 5m away from combustible buildings and to keep it at least 3m away from fire-resistant buildings. There should be a minimum distance of 5m between the substation and the ground and a minimum distance of 1m between the low-voltage distribution box and the ground.
All exposed live parts on the transformer platform should be at least 5m above the ground, and warning signs should be set up in obvious locations 2.5 to 3.0m above the ground.
