Product Parameters

1. Product description:

As an important power supply unit in the cabled distribution network,ZGS11-10 is a  complete preinstalled product that integrates high-voltage control,protection, substation,and distribution equipment and is widely used in urban and rural distribution networks.

This product places high-voltage load switches and high-voltage fuses in transformer oil,and has two structural forms:co box or sub box with the transformer body.

The oil tank adopts a fully sealed structure,equipped with an oil temperature gauge and oil level gauge.Components such as pressure gauges,pressure relief valves,and oil drain valves are used to monitor the operation of transformers.This product is divided into ring network,terminal,and power supply modes.n order to make this product more suitable for the actual requirements of China's power grid,the company has also introduced plug-in dry type fuses,and the melting of the fuse does not affect the   performance of transformer oil.According to the complexity of low-voltage feedback requirements,ZGS11-10  products are divided into three shell forms: standard,reinforced and comprehensive,allowing users and design units to achieve more flexibility and economy in selection.
