Insulated Type Extension Rods can be screwed together for allowing circular brushes to be used for internal pipe testing. These Extension Rods are also used for extra length of pipe inspection from external or internal sides. These Extension Rods are able to carry voltage of up to 40 KV and available in both 0.5 and 1 meter lengths. Insulated Type Extension Rods can be used for internal coating inspection using high voltage holiday detectors.
