High Voltage Fuse

(Product Usage)

This series of product is applied to power system with indoor AC 50 Hz-60Hz, rated voltage being 3.6 Kv-40.5 Kv, and it could be cooperation-used with other protection electric device (such as vacuum connector, load switch ect) to be overload or short circuits protection components of high-voltage motor, power transformer, instruments transformer, and other electrical equipment.

Product characteristics of new high-voltage limit-current fuse

• The high-Volt current-limit fuse of our company are the high-quality products with world advanced leve which are developed on basis of absorbing the same product's advantages domestical and abroad. This product owns the following characteristics:
• with high broken-ability,the broken current can achieve 63 KA.
• Small power-consumption,low temperature-rising.
• with fast motion properties, its ampere-second performance is faster than domestically produced product of same kind at present.Taking fuse component with rated current being 100A for example, the pre-arc time doesn't exceed 0.1 Sif electrified with 1000A anticipated current.
• The ampere-second per for man ce error is with in ± 10 %
• Matched with spring type collision device.this collision device own properties of big contacted surface and small intensity of pressurc. Consequently,smashin g or puncturing switch and striker would not occur when operator pushes switch for link-lock motion.
• Specification standardization.
• Own big limit-current function.
• The product's performance is up to GB 15166.2 and IEC 60282-1 standard.
• Could break down reliably any fault current from minimum broken current to rated broken circuit, additionally our company could produce various non-standard product awarding to user's demand.
