What is the 35kV Pole–mounted Three–phase Transformer?

35 kV Pole-mounted Three-phase Transformer is a high-voltage electrical device for installation on utility poles typically used in medium voltage power distribution networks. This type of transformer operates at a rated voltage of 35kV and, in this dimension, the step down of electrical energy from higher transmission voltages to the levels required locally for distribution is efficient. Relying on three phases of configuration, its balanced power delivery makes it a necessity for industrial and commercial applications that depend on stable and efficient energy delivery. The transformer has been designed focusing on compactness and durability to withstand environmental outdoor conditions. Typically enclosed and corrosion-resistant materials are used to achieve long-term reliability in a variety of climates including those of extreme weather. Space saving is another strong benefit since the pole mount installation does away with the need for ground-based transformer pads and reduces the risk of unauthorized access or accidental damage.

Features

A robust and compact Pole Mounted Three-phase Transformer is specially designed for outdoor pole installations at 35kV. Made of high-grade, grain-oriented silicon steel in its core to minimize energy losses and ensure the right magnetic flux distribution. Copper or aluminum windings are made and insulated with good materials capable of withstanding thermal and electrical stresses during constant application at high voltages.

The transformer’s outer casing is made of corrosion-resistant materials like galvanized steel or special coatings, to withstand environmental elements of rain, humidity, UV radiation, and temperature changes in the long term. The design also includes neat mechanisms for cooling, like radiators or fins, that have been integrated alongside optimal heat dissipation. This provides a stable operating condition under different loads.

The transformer uses high-performance insulating oil not only as an electrical insulator but also as a cooling medium. Porcelain or composite bushings are durable, prevent leakage currents, and resist mechanical and electrical stresses. There are mounting brackets and hardware engineered for secure and stable attachment to utility poles, to resist mechanical vibration, wind loads, and seismic forces.

The hermetically sealed construction prevents contamination and moisture ingress and includes additional features, such as integrated protection systems, e.g., pressure relief valves and oil level indicators, to increase operational safety and reliability. This engineered structural design ensures good transformer performance, without the need for frequent maintenance, resulting in a reliable component in a medium voltage distribution network.

Is it environmental protection compliant?

Designed with sustainable environment standards in mind, the 35kV pole-mounted three-phase Transformer has planned for environmental standards. Its construction materials and operational features are in tune with eco-friendly practices and have less environmental footprint. During operation, energy losses are significantly reduced through the transformer core, which is made from grain-oriented silicon steel (or amorphous alloy silicon steel) reducing energy use by improving energy efficiency and lowering carbon emissions.

This is hermetically sealed oil tanks and prevents insulating oil leakage from contaminating the surrounding environment. Furthermore, the insulating oil is usually nontoxic or biodegradable, as is often the case with transformer maintenance and operation. Specialized core construction and damping coatings reduce noise pollution, a property that allows the product to be installed in environmentally sensitive and residential areas.

Under normal conditions, the transformer is engineered for long-term durability, with minimal life cycle resource consumption. The International Standards, such as IEC and IEEE, facilitate the compliance and guarantees of the standards by meeting stringent environmental and performance requirements. This combination of energy efficiency, safety, and low maintenance makes it an environmentally responsible choice for considering in modern power distribution networks.
