HDCR-12 10kv 12KV 200A 400A 630A Outdoor High Voltage Porcelain Disconnector
Product Overview
The HDCR-12/630 HGW10-12/630 outdoor single pole isolation switch is a single-phase, pole-mounted device designed specifically for outdoor use. It offers a distinct advantage by providing a clearly visible break, which is crucial for maintenance personnel to ensure safety during inspections and repairs. Additionally, it functions effectively as a break point in electrical circuits.
This isolation switch features a double column structure. Insulators and bolts are securely fastened to a base that has undergone hot-dip galvanization for anti-corrosion treatment. Operation is straightforward; simply pulling the pull ring allows for easy activation of the switch. By default, the isolation knife opens to a limit of 160 °, but this can be adjusted to 90 ° on-site or even removed for unrestricted movement.
When it comes to installing the DWR-12/630HDMR isolation switch, an optional installation backplane is available. This backplane can be conveniently clamped onto the crossbar, providing a stable and secure way to fix the switch in place during the installation process.
