Description

Technical Field

[0001] This utility model relates to a touchable European-style insulating cap. Background Technology

[0002] Touchable European-style insulating caps are protective devices used in high-voltage power equipment. They provide fully sealed insulation protection for live interfaces and offer dustproof and moisture-proof sealing for non-energized interfaces.
