Product Description

The 5mva 12 kv amorphous metal alloy transformer is a new generation of excellent efficient and energy saving power equipment. It uses iron based amorphous alloy strip as the core material , making it an ideal upgrade replacement product for traditional silicon steel transformers. It is suitable for scenarios such as urban and rural distribution networks, industrial parks, and new energy power stations.

It has the following features:

1. Extremely low loss, significant energy saving. The core of 5mva 12 kv amorphous metal alloy transformer is made of 0.027mm ultra thin iron based amorphous alloy strip material, with high magnetic permeability and extremely low eddy current loss. The no load current is reduced by approximately 85% compared to traditional S9 silicon steel transformers, and the energy saving effect is particularly prominent during long term light load operation, aligning with the "dual carbon" goals.

2. High quality material, stable and durable. The core uses a three phase three column wound structure without seams, with strong anti magnetic saturation and anti vibration performance, and a long service life. The windings of 5mva 12 kv amorphous metal alloy transformer use high purity oxygen free copper wires, combined with insulating paper, with high insulation strength and strong anti short circuit impact capacity.

3. Low noise, environmentally friendly, and suitable for a wide range of applications. The whole operating noise of 5mva 12 kv amorphous metal alloy transformer is ≤ 52dB, lower than that of traditional transformers, meeting the low noise requirements of residential areas, commercial buildings, etc. The fully sealed design has no leakage, the materials are environmentally friendly and recyclable, reducing operation and environmental protection costs.

4. Safe and reliable, easy to maintain. Standard accessories include gas relays, pressure release valves, winding temperature gauges, etc., with overvoltage, overheating, and short circuit protection functions. The fully sealed structure reduces daily maintenance and has lower total life cycle costs.

Q: Does 5mva 12 kv amorphous metal alloy transformer require special maintenance?

A: It does not require special maintenance and is overall more worry free and requires less maintenance than ordinary silicon steel transformers. All that is required is regular visual inspections, cleaning and dust removal, as well as checking for oil leakage (for oil immersed transformers); regular temperature measurements, checking the tightness of connection terminals, and ensuring that the temperature control and protection devices are functioning properly; conducting annual preventive tests in accordance with the conventional transformer procedures; and maintaining a well ventilated, dry environment without excessive heat, direct sunlight or water accumulation.
