Our safety insulating covers are high-performance silicone rubber protective shields designed to insulate exposed live parts on distribution equipment and overhead lines. They prevent accidental human contact, animal-caused phase-to-phase and phase-to-ground short circuits, bird nesting faults, and pollution flashover — significantly improving the safety and reliability of 10kV–35kV distribution networks. Each cover is precision-molded to fit specific equipment, with a snap-on design for fast tool-free installation.

Product Range

• Transformer Bushing Covers — Shield HV and LV bushings of pole-mounted and pad-mounted transformers.
• Surge Arrester Covers — Insulate arrester terminals and connection points.
• Drop-Out Fuse Covers — Cover live terminals and fuse holder contacts.
• Disconnector Covers — Shield fixed and moving contacts of disconnectors.
