SCB series dry-type transformers with epoxy insulation 10 kV are manufactured by vacuum casting with epoxy resin. They are especially suitable for use in urban electrical networks, high-rise buildings, hospitals, airports, subways, tunnels and other places with increased safety and environmental requirements.
Oil-filled transformers 10–20 kV are made using a fully sealed corrugated tank and vacuum oil filling technology. They are characterized by stable and reliable operation, effectively slow down the aging of insulation and reduce maintenance costs.
KKSG Mine dry transformers for general purpose have such advantages as safety, reliability, energy efficiency, fire safety, explosion protection, absence of harmful gas emissions, environmental friendliness and ease of maintenance.
The American ZGS type complete transformer is a product widely used in power distribution systems. Unlike the European complete transformer, it is not a simple combination of a transformer and high-voltage and low-voltage cabinets, but is a complex electrical device developed on the basis of a transformer.
The JP series multi-function outdoor distribution cabinet (hereinafter referred to as “JP cabinet”) is an integrated electrical device specially designed for the modernization of urban and rural electrical networks, as well as for 0.4 kV low-voltage distribution systems.
Integrated converter unit for energy storage systems - step-up transformer. By integrating two converters for energy storage systems and a step-up transformer, the overall system footprint is reduced, equipment manufacturing and transportation costs are reduced, assembly and end-to-end on-site setup time is reduced, and installation and maintenance efficiency is increased.
One of the important technologies in high-voltage variable frequency technology is multi-stage summation technology, which uses an isolation transformer to connect several low-voltage modules in series to form a high-voltage output.
ZS type oil rectifier transformer is a special transformer designed for rectifier applications, which uses insulation oil for insulation and cooling. It converts AC mains voltage into voltage suitable for rectification, which is then supplied as direct current through rectifier elements.
The European-style cable drop cabinet, usually designated starting with DFW (such as DFW-12), is a key device widely used in power distribution systems.
American type cable branch cabinet is a characteristic cable connection device in power distribution systems. Its design concept originated in North America and is now also widely used in industrial parks, shopping malls and densely populated urban areas in China.
