Power equipment insulation shields are transformers, arresters, outdoor switches and other power equipment terminals, must be equipped with insulation safety protection products, this product can effectively prevent the original exposed power equipment terminals, due to various reasons (man-made Power outages and electric shock accidents caused by contact, electricity theft, small animals or debris, wet flash salt spray and chemical gas corrosion, etc.), so as to avoid huge economic losses caused by this, it is a new product promoted by the country; silicone rubber Electrical contact safety shields, Hz-series shields are good electrical insulation, waterproof and sealing safety protection products. It has the characteristics of convenient installation, excellent environmental adaptability and long service life; it is mainly used for electrical contact insulation protection and safety protection of electrical equipment such as power transformer terminals. Eliminate short-circuit accidents caused by foreign objects overlapping animals crawling; prevent personal electric shock, pollution and condensation flashover; reduce the corrosion of conductive materials by air and harmful gases, and prolong the service life of electrical equipment.
