Company Profile
Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
Product Description
The fuse is composed of a melt tube, a porcelain sleeve, a fastening flange, a transverse post insulator and a terminal. The terminal caps and melt tubes at both ends are fixed in the porcelain sleeve by pressing, and then the porcelain sleeve is fixed on the rod post insulator with a strong flange.
In the melt tube, high silica content is used as the extinguishing medium, and small diameter metal wire is used as the fuse. When the overload current or short-circuit current passes through the melt tube, the fuse is immediately broken, the arc occurs in several parallel narrow gaps, the metal steam in the arc penetrates into the quartz sand, is strongly free, and the arc is quickly extinguished. Therefore, this fuse has good performance and large breaking capacity.
High voltage fuse is suitable for short circuit and overload protection of transmission lines and power transformers, and is a simple electrical appliance to protect power equipment from damage.
High voltage fuse is suitable for 1000 meters above sea level, the ambient temperature is not higher than +40ºC, not lower than -40ºC, not suitable for combustion, explosion risk, violent vibration, swing impact places and heavy pollution areas.

Installation Notes
1. Fuses allow horizontal or vertical devices.
2. The fuse replaces the RW2-35 high voltage fuse and XJ-35 current limiting resistor, so it should be noted that when the data of the melt tube is inconsistent with the service voltage and rated current of the line, it should not be connected to the line.
3. After the fuse is blown, the user can replace it by himself, disassemble the wiring cap, and replace the melt tube with the same specifications and performance requirements. The replacement procedure is as follows:
(1) First screw out any end of the wiring cap screw.
(2) Open the wiring cap and take out the compression spring and the blown pipe.
(3) Replace the new melt tube and add a compression spring to tighten the wiring cap screw.
