The 250A insulating cap provides insulation and sealing protection for the 250A casing, and provides dust and moisture protection for the uncharged casing. When there is a spare outlet, a 250A insulating cap must be installed to seal the casing. After the insulating cap is installed, use the pull hook to tighten the insulating cap to prevent it from loosening, so that the system is safer and more reliable.
HYJYM-10(20)/630 insulating cap is mainly used to provide insulation protection (permanent or temporary) for live 10kV or 20kV bushings, and to provide dust-proof and moisture-proof sealing for uncharged bushings and busbars.
