embedded pole circuit breaker is an indoor medium-voltage circuit breaker in which key components such as the vacuum interrupter (or other interrupter), main conductive circuit, and insulating supports are encapsulated in epoxy resin (or other high-performance insulating materials) using an automated pressure gel (APG) process.
feature of Embedded Pole VCB
The term "embedded pole" means that the main circuit breaker components are fixed in a highly insulated and robust module.
Common pressures for solid-encapsulated circuit breakers are 12kV (10kV) and 24kV, and they are one of the mainstream products in the current medium-voltage power distribution field.
Solid-encapsulated circuit breakers are often used as solid-encapsulated vacuum circuit breaker modules in metal-enclosed armored withdrawable switchgear (such as the KYN28A-12 type medium-voltage switchgear) or fixed switchgear.
A common insulated cylinder circuit breaker (often referred to as an "air-insulated" or "open" circuit breaker) refers to a circuit breaker whose vacuum interrupter (or SF6 interrupter) is not encased in epoxy resin, but rather exposed or semi-exposed within a cylindrical casing made of insulating material (such as polyester, epoxy resin, SMC, etc.). This insulating cylinder primarily serves for phase-to-phase insulation, ground insulation, and mechanical support, but most of the space inside remains air.
A common Insulated cylinder VCB feature
A common insulated cylinder circuit breakers utilize a separate "interrupter chamber + insulating cylinder" combined structure. The interrupter and insulating cylinder are independent components and can be replaced separately.
A common insulated cylinder circuit breakers are widely used in early metal-enclosed armored withdrawable switchgear (such as older cabinet types like KYN1 and KYN18) and fixed load switchgear. It represents an important development in vacuum circuit breaker technology.
