Boots & right-angled boots with medium voltage provide enhanced phase-to-phase and phase-to-ground insulation at cable lug-to-bushing connections. Furthermore, made from crosslinked polymers, they offer excellent dielectric strength and resist tracking, erosion, and environmental stress. As a result, ideal for tight air clearances and harsh conditions, they ensure reliable, long-term protection for switchgear and transformer cable boxes.
