A single lineworker can easily cut large-gauge conductors with the power-assist of this tool’s closed hydraulic system. It operates like a hydraulic jack, by simply pumping the handle. Epoxiglas® pole, handle and hydraulic hose have been tested to 100kV per foot. Hydraulic oil has dielectric strength of more than 25kV per ASTM D877. Hose has minimum burst strength of 12,000 psi. Pump provides 9,000 psi maximum pressure.
