switchgear, substation, circuit breaker

Product Description

Switchgear is a familiar kind of electrical equipment using in the power electric system, such as power plant, substation, factory or civil construction. We can supply high, medium and low voltage switchgears, also GIS (Gas Insulated Switchgear) and Ring Main Units. Circuit Breaker is a device that quickly breaks its electrical connection, protecting an electrical apparatus from damage caused by short circuit or overload. We can supply Vacuum Circuit Breaker (VCB) up to *0.5kV, SF6 Circuit Breaker below **0kV, Air Circuit Breaker (ACB) and other types of circuit breakers. A Transformer is connected between the source and the load, the voltage can be decrease (stepped down) and the current increase (stepped up). We can supply oil-immerged power transformers (Voltage up to **0kV, Capacity below ***0MVA), dry-type transformers (Voltage below *6kV, capacity up to *0MVA), American type cabinet transformers, European type cabinet transformers and so on. The tap changer can be OLTC or NLTC. Mainly we are dealing with cut-out fuse which also named rop-out fuse some time, the primary purpose of any fuse cutouts is to provide protection to the lines of system and the various apparatus on those lines such as transformers and capacitor banks. it provide reliable protection from low-level overloads that just melt the fuse link, intermediate faults, and very high faults, through maximum interrupting capacity. We offer the range from *5 to *6kV products, material is made by both porcelain and silicon rubber.
