OverviewThe LPA000-02120-01PE Large Volume Series slip ring is a high-power, large-current rotating electrical interface designed for drill poles on oil drilling platforms. It enables reliable 360° rotary high-voltage transmission in a compact, vertically mounted, high-sealing, explosion-proof structure. Contact system uses copper-graphite (carbon brush) materials and the housing is made from stainless steel 316 / 42CrMo. The product is covered by a Chinese patent and can be returned to the factory for maintenance if required.
Significance- Raises the technology standard of slip rings for mining and oil-drilling equipment.
- Proven by high sealing pressure tests to improve cable sealing reliability in harsh downhole environments.
- Delivers a practical solution for electrical transmission on oil drilling systems.
Technical breakthrough- Enables reliable 360° rotary high-voltage transmission within a compact structure.
- Eliminates sealing issues caused by wire leads routed through the drill rod.
- Integrated explosion-proof features suitable for hazardous environments.
