Product Launch – MV Medium Voltage Static Ground Discharge Stick
Thorne & Derrick supply the CATU CM-50 Static Discharge Stick used for medium/ high voltage overhead lines, busbars and substation use up to 33kV. The CATU discharge stick complies to the IEC 60855 standard and is used to safely dissipate electrostatic charges.
♦ IEC 60855-1:2016 Standard | Live Working – Insulating foam-filled tubes and solid rods. Part 1: Tubes and rods of a circular cross-section.
CATU CM-50 static discharge stick is an insulating orange tube with a diameter of 39mm and made of epoxy fibreglass – equipped with 6 metre of copper cable, cross section section 6sqmm, PVC insulated.
Static discharge sticks are designed to safely remove the static charge after de-energising of medium/high voltage power systems – this includes draining voltage retaining components before maintenance work is performed up to 33kV. The discharge sticks are equipped with hand guard and grip protection with sufficient electrical safety clearance against physical contact with medium/high voltages.
Static discharge sticks are available for higher voltage applications – contact us to discuss your MV HV EHV Electrical Safety Equipment requirements.
