Product descriptions from the supplier
The CYD-4 series hydraulic disc spring operating mechanism uses disc springs as energy storage components. Disc springs have excellent force characteristics, are not affected by environmental temperature, store a large amount of energy, and have smooth force characteristics. Its structure adopts an integrated module design without pipeline connections. Adopting advanced sealing structure design, advanced dynamic and static sealing systems, internal integrated hydraulic buffer system, high system pressure, compact structure, high operating power, stable and reliable performance. Mainly suitable for high voltage and high current applications in GIS dead and tank circuit breakers with voltage levels of 252kV-1000KV.

Analysis and Remedial Measures for Insulation Failures in Power TransformersThe Most Widely Used Power Transformers: Oil-Immersed and Dry-Type Resin TransformersThe two most widely used power transformers today are oil-immersed transformers and dry-type resin transformers. The insulation system of a power transformer, composed of various insulating materials, is fundamental to its proper operation. A transformer's service life is primarily determined by the lifespan of its insulating materials (oil-paper or resin).In practice, most transformer failures result from damag12/16/2025 -
Case Studies of Installation and Manufacturing Defects in 110kV HV Circuit Breaker Porcelain Insulators1. SF6 gas leakage occurred in the ABB LTB 72 D1 72.5 kV circuit breaker.Inspection revealed gas leakage at the fixed contact and cover plate area. This was caused by improper or careless assembly, where the dual O-rings slipped and were misplaced, resulting in gas leakage over time.2.
