Energy on the pole, power at heart – Single-phase pole-mounted transformer, making electricity outstanding.
01 General
1.1 Project Description
SCOTECH is glad to provide a high-quality single-phase pole mounted transformer for the Canadian Public Service. The single-phase transformer has a capacity of 100kVA, the primary voltage is 7.97/13.8Y and the secondary voltage is 0.12/0.24kV, which can easily meet local electricity demand. The single phase pole mounted transformer converts the voltage of the grid into the voltage required by the system or load, and realizes the transmission and distribution of electric energy. The large-scale operation of this product can achieve a good energy saving effect and reduce air pollution. This product is especially suitable for power shortage and load fluctuation and difficult to carry out daily maintenance in areas. Because the transformer adopts a fully sealed structure, insulating oil and insulating media are not polluted by the atmosphere, so it can operate in a humid environment, and is the ideal distribution equipment in the vast distribution network in cities and rural areas. Single-phase transformers are especially suitable for rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting and power consumption. can also be used for railway, urban power grid energy-saving transformation column type distribution lines, can be single-phase operation or three single-phase groups as three-phase operation.
Our 100 kVA pole mounted transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.

02 Manufacturing
2.1 Core
| The advantages of transformer coil core are mainly reflected in its excellent electromagnetic performance and efficient energy transmission capacity. The efficiency of the transformer is improved because the winding process reduces the air gap and loss. This design helps reduce noise and vibration and improves overall performance. Coil core can effectively reduce eddy current loss due to its uniform flux distribution. In addition, the rolling process provides a tighter structure, improves mechanical strength and durability, and ADAPTS to high temperature and humid environments. The coil core also reduces noise and vibration in operation, making the equipment more stable, able to adapt to various working environments, and extending the service life of the equipment. |  |
2.2 Winding
As a part of the winding, the low-voltage foil winding can effectively shield the electromagnetic field of the high-voltage winding, thus reducing the influence of electromagnetic interference (EMI). When the transformer shares space with other electronic devices, it can reduce interference between electronic devices and improve the electromagnetic compatibility of the overall system. As a part of the winding, the low-voltage foil winding can effectively shield the electromagnetic field of the high-voltage winding, thus reducing the influence of electromagnetic interference (EMI). When the transformer shares space with other electronic devices, it can reduce interference between electronic devices and improve the electromagnetic compatibility of the overall system. Due to the structure characteristics of low-voltage foil winding, it can effectively disperse the local heat generated by short circuit fault, reduce the risk of instantaneous impact of short circuit current on the winding, and improve the safety and reliability of the transformer. The rational layout of low-voltage and high-voltage winding design can effectively reduce the phenomenon of magnetic leakage and further improve the energy efficiency and performance of the transformer. By optimizing the arrangement between the windings, better flux coupling can be achieved, thereby improving the overall efficiency of the transformer.
2.3 Tank
 | According to the design drawings, the equipment such as a plasma cutting machine, laser cutting machine or water knife, is used to cut the metal sheet material into various parts of the tank, including the bottom plate of the tank, the side wall of the cylinder, the top cover, etc. The cut metal plate is processed into a cylinder shape by a rolling machine to ensure that the outline is rounded and meets the design standard. The individual components of the tank are fully welded using processes such as gas shielded welding (MIG welding) or arc welding, and the welds should be uniform and smooth and have good sealing. After welding, the surface of the tank should be decontaminated to remove welding slag, oxide layer and oil. Anti-corrosion coatings are sprayed on the outside of the tank to prevent corrosion caused by environmental impacts in daily use. The inner wall can also be treated with anti-corrosion to increase the service life of the insulating oil. |
