Description

Our RSW Type Pole-Mounted Load-Break Switch (Pole-LBS) is a high-performance power distribution switch engineered for up to 24kV, 400/630A, 50Hz applications, paired with a state-of-the-art controller for versatile operation. Available in SF6 gas-insulated and vacuum-insulated variants, this pole-mounted switch seamlessly integrates with distribution automation systems, enabling remote line isolation and smart grid management from a control center.

Designed for quick, low-cost pole-mount installation and rugged all-weather performance, it supports both manual and electronic operation, with optional CT/PT integration and smart controller pairing for a multifunctional smart sectionalizer solution.

Core Features

Dual insulation type options: Available in SF6 gas-insulated and vacuum-insulated variants, the former delivers superior insulation and arc quenching performance, while the latter features eco-friendly properties and low maintenance requirements.
Advanced smart grid integration: Pre-configured with a state-of-the-art electronic controller, it seamlessly connects to distribution automation systems, enabling centralized isolation of distribution line sections and efficient network management from the control center.
Simplified pole-mount installation: Adopts a streamlined mounting structure for quick on-site assembly, significantly reducing labor input and overall installation costs for outdoor projects.
Dual operation modes: Supports both manual and electronic controller operation for flexible on-site use, with optional wired/wireless modems mountable in the cabinet to enable full remote monitoring and control functions.
All-weather durable design: The electronic controller is enclosed in a stainless steel cabinet, specially engineered to withstand all outdoor weather conditions and ensure stable operation in complex environments.
Smart sectionalizer capability: The vacuum-insulated variant can be combined with CT/PT and a smart controller to form a smart sectionalizer, a multifunctional load-break switch equipped with advanced relay protection and communication features for modern intelligent power distribution needs.
