High And Low Voltage Switch Cabinet Electrical Components

Jun 07, 2020

The primary electrical components (main circuit equipment) commonly used in high and low voltage switchgear cabinets are as follows:

Current transformer abbreviation CT [such as: LZZBJ9-10]

Voltage transformer referred to as PT [such as: JDZJ-10]

Grounding switch [eg: JN15-12]

Lightning arrester (resistance capacitance absorber) [eg: HY5WS single-phase type; TBP, JBP combined type]

Isolation switch [eg: GN19-12, GN30-12, GN25-12]

High-voltage circuit breaker [eg: oil-less type (S), vacuum type (Z), SF6 type (L)]

High voltage contactor [such as: JCZ3-10D/400A type]

High voltage fuse [eg: RN2-12, XRNP-12, RN1-12]

Transformer [eg: SC (L) series dry transformer, S series oil transformer]

High voltage live display [DXN-Q type, DXN-T type]

Insulation parts [eg: wall bushings, contact boxes, insulators, insulation heat shrink (cold shrink) jackets]

High voltage reactor [such as series type: CKSC and starter motor type: QKSG]

Load switch [eg: FN26-12(L), FN16-12(Z)]

High-voltage single-phase parallel capacitors [eg: BFF12-30-1] etc.
