Protection Cover IP21

Based on the characteristics of the usage environment and the protection requirements, SC(B)10 13.8kv 50kva transformers epoxy cast resin can be equipped with different enclosures. Usually, an IP23 protection enclosure is selected, which can prevent foreign objects with a diameter greater than 6mm and small animals such as rats, snakes, cats, and sparrows from entering, thus avoiding serious faults like short circuits and power outages. It provides a safety barrier for the live parts.

Transformer Under Test

If the SC(B)10 13.8kv 50kva transformer epoxy cast resin needs to be installed outdoors, an IP23 protection enclosure can be chosen. Besides the aforementioned IP20 protection function, it can also prevent water droplets at an angle of 60°or less from entering with the vertical line. However, the IP23 enclosure will reduce the cooling capacity of the SC(B)10 13.8kv 50kva transformer epoxy cast resin. When choosing it, attention should be paid to the reduction of its operating capacity.

Specifications and Process:

This SC(B)10 13.8kv 50kva transformer epoxy cast resin uses a mature vacuum pressure casting process for its windings. After the winding is completed, it is placed in a special mold, undergoes high vacuum degassing treatment to completely eliminate bubbles, and then is formed through integrated impregnation and segmented stepwise curing. The overall structure is compact and uniform, with the partial discharge quantity strictly controlled within 5pC, fully meeting the insulation requirements for medium voltage power distribution equipment.

Finished Product

The windings are completely enclosed by epoxy resin, with no capillary gaps inside, and have excellent moisture proof capabilities. They can operate stably in an environment with a relative humidity not exceeding 95% and without condensation for a long time. After the SC(B)10 13.8kv 50kva transformer epoxy cast resin is shut down for a long time, there is no need for preheating and dehumidification, and it can be directly powered on and used. At the same time, the epoxy surface layer is smooth and dense, which can effectively prevent dust and particulate matter from invading the insulation interior. Combined with the standard IP20 protection housing, it can also be upgraded to a higher protection level according to the on site conditions, suitable for complex usage scenarios such as dusty and humid environments. The entire machine has strong environmental adaptability and simple and convenient daily operation and maintenance.
