XRNT4-8.3kV ELSP current-limiting backup fuse 30A 53mm*152mm

1.Product description

XRNT4- 8.3,XRNT4- 9.9,XRNT4- 15.5, XRNT4-17.2,XRNT4-23, XRNT4-38series high-voltage current limiting fuse for oil-immersed transformer protection. It is suitable for use in power systems with AC rated frequency 50Hz and rated voltage8.3 KV, 9.9KV, 15.5 KV, 17.2KV, 23kV and 38 KV respectively. As a protection element for short-circuit faults of power transformers and other power equipment, the fuse is installed in the transformer oil of American-style box transformers or other box transformers, and can be co-boxed with transformers and load switches. The high-voltage current-limiting fuse can be connected in series with the transformer overload protection high-voltage fuse to form a full range of high-voltage current-limiting fuse. When the overload current exceeds the specified value for a certain time, the circuit is opened by the overload high-voltage fuse. When the short-circuit current passes through the fuse, the short-circuit current is opened by the backup high-voltage current-limiting fuse. The product can be widely used in the distribution protection of wind power generation, solar power generation, tide stream power generation and other equipment.This product has no pollution to the transformer when opening the current. It has stable time-current characteristic curve, remarkable current limiting characteristic of backup fuse and strong breaking capacity up to 50kA.

Xian Hao Sheng Electrical Equipment Manufacturing Co., Ltd. is a large fuses manufacturer in China specialized in researching and manufacturing the high-voltage current-limiting fuses.

We adopt the advanced manufacturing technology, process and testing equipment and quality management system to develope unique first-class products with the trustworthy after-sales service.

Our "Hao Fang" high-voltage current-limiting fuse pass through the National Quality Supervision and the Testing Center Electrical type tests, in 2003 the company passed ISO 9001 international quality system certification. The performance of products have reached the national standard (GB15166.2) and the International Electrotechnical Commission standard (IEC60282-1), and in accordance with British Standard BS and German DIN standards.

The main products are covered by 3.6kV ~ 40.5kV voltage level of various specifications of high-voltage current-limiting fuse Which is divided into four major series of more than 70 kinds of specifications. They are transformers protected high-voltage current-limiting fuses, electric motors capacitor protected high-voltage current-limiting fuses, voltage transforer protected high-voltage current-limiting fuses and a full range of high-voltage current-limiting fuses.

The products are standardized, serialized, small sizes and diversification.

"Hao Fang" brand fuses has high breaking capacity (50kA), short break time, less power consumption, low over-voltage, stability characteristics and equipped with modern sealed impactor (the energy of 2 ~ 5 J).

They are essential accessory products for box-type transformer substation, high voltage load switch, high-voltage contactors and other.

They are used together with the load switches, contactors as a replacement of expensive circuit breakers ideal, can greatly reduce the substations, power equipment investment costs.

And primarily serve for the systems of the electric power, metallurgy, mining, oil and other transmission and distribution systems.
