The RDS‑series outdoor high‑voltage disconnector adopts a V‑arrangement double‑post center‑break design. Two rotating post insulators are installed on one common base at 50° angle; the operating mechanism drives one insulator, and angular gears or linkages drive the other insulator to reverse‑rotate, forming a horizontal visible isolating gap for opening and closing operations.
The RDS‑series outdoor high‑voltage disconnector is equipped with self‑contained special copper‑alloy contacts. It relies on the inherent elastic force of the contact itself to achieve tight connection, removing contact springs.
This avoids common risks such as spring corrosion, shunting, overheating and rising contact resistance caused by spring failure.
The rotating base of the RDS‑series outdoor high‑voltage disconnector uses fully sealed construction to block moisture, dust and harmful gas ingress.
Its bearing is filled with non‑leaking, non‑hardening low‑temperature lubricant. Thrust and radial ball bearings jointly bear gravity and horizontal loads, keeping stable operating torque throughout the whole service life with little routine maintenance.
Yes, the RDS‑series outdoor high‑voltage disconnector can be deployed in Class IV heavy‑pollution areas with high creepage‑distance requirements.
It is widely used in transmission‑distribution substations, industrial power systems, grid interconnection stations and overhead‑line termination occasions under harsh environmental conditions.
