High Voltage Shields

HVS Series (High Voltage Shields) are a safety device directly related to the safety of company personnel, and are intended to cover electrical high vacuum feedthroughs which are based on typical Mini 1-1/3" OD and 2-3/4" OD MET-SEAL style flanges.

Features

HVS Series simply are attached via 2 each socket head cap screws located on the aluminum split clamp, which secures directly to the electrical feed through flange OD.

The shroud itself is clear scratch resistant acrylic; the cord grips are standard liquid tight strain reliefs which are intended to seal cable entries and keep contaminants from entering the enclosure.

Maximum temperate ratings -40º to + 150º F

Safety and convenience

When properly installed, HVS shrouds can safeguard operators from possible accidental electrocution, as the acrylic material is an excellent electrical insulator. Alert people, develop safety practices, and help keep your workplace safe by alerting people to potential hazards with proper accident prevention. "Danger High Voltage" label located on the OD of the shroud clearly indicates an imminently hazardous situation, which if not avoided, can result in serious injury or death. Along with increasing machine safety, an additional benefit is gained by the protection of fragile components and instruments.
