Sheath Voltage Limiters | LV Low Voltage 120V
Sheath Voltage Limiters
LV |120V
The Sheath Voltage Limiter (SVL0.12) manufactured by PD Devices Ltd is designed for installation across insulating gaps that cannot be directly bonded, with a rated sheath low voltage of 120V – the SVL’s are encased in adhesive-lined heat-shrink tubing to provide an IP68 Protection Rating.
The SVL device features tinned copper mounting and 316 (A4) stainless steel fixings, making it suitable for harsh environments. This unit comes with the standard fixing kit (425-1-0062), and other SVL voltage ratings and fixing kits are available upon request.
Thorne & Derrick are suppliers of Sheath Voltage Limiters, which provide overvoltage protection of Power Transmission & Distribution underground cable sheaths – this includes MV HV Medium & High Voltage Cables according to the rated voltage of the SVL’s (Sheath Voltage Limiters). We can provide excellent customer support, product selection and competitive prices with next-day delivery from extensive stocks of electrical Link Boxes.
