1.What is a pole mounted transformer?
Pole mounted transformer is a type of oil immersed sealed distribution transformer. Pole mounted transformer is a distribution transformer installed on a telephone pole made of wood or concrete. Usually the structure of power pole transformer is cylindrical and rectangular.
2.Pole mounted transformer Application:
Pole mounted distribution transformers are widely used in rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting, and energy-saving transformation of railways and urban power grids. It is also suitable for applications in power distribution systems such as light commercial loads and industrial lighting.
3.Pole mounted transformer Working principle:
1.Pole mounted distribution transformer usually have two windings, primary and secondary. The current passes through the primary coil to generate a magnetic field to form the principle of mutual induction. The magnetic field passes through the secondary coil to generate an electromotive force, and an increased or decreased voltage is obtained in the secondary coil.
2.Telephone pole transformer convert circuit voltage to 120/240 volt power for use in homes and small capacity commercial facilities.
4.Pole mounted transformer Function:

12.Single phase pole mounted transformer type:
• Power Pole transformers are mainly divided into traditional pole-mounted transformers and single-phase overhead completely self-protected (CSP) pole-mounted distribution transformers.
Conventional type: A pole-mounted transformer composed of two primary bushings is usually called the "traditional type". It mainly consists of a active part, a fuel tank, high and low voltage bushings, eye bolts, connecting terminals, earthing devices, hooks, and support lugs. composition.
• Single-phase pole-mounted transformers are common oil-immersed distribution transformers in the United States, Japan, Canada, Philippines, Australia and other countries. Due to their small size and light weight, they are usually installed on the top of utility poles. Widely used in homes and small capacity commercial facilities as well as remote areas.
CSP single-phase pole-mounted transformer: CSP is a transformer that contains multiple protection devices such as arresters, fuses and circuit breakers. It can achieve complete self-protection and avoid current faults caused by its own faults under the influence of lightning and short circuits. to ensure the safety of distribution lines.
