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.
FLN36- 12D/T630-25 indoor AC high voltage SF6 load switch and FLRN36- 12D/T1250-31.5 indoor AC high voltage SF6 load switch fuse combination apparatus is suitable for three-phase 50Hz ring network or terminal power supply and industrial electrical equipment, for protecting the line of 10kV Electric Power Load Control System.
The load switch can be divided into load current, closed loop current, no-load transformer and cable charging current;
The combined apparatus is capable of breaking any current which is reach to rated short circuit, and is suitable for the electrical equipment of the ring network unit, the box type substation and so on.
The utility model is especially suitable for places such as the distribution of the urban residential areas, the small two substations, the opening and closing stations, the industrial and mining enterprises, large shopping malls, airports, subways, hospitals, stadiums, etc.

2. Altitude: not exceed 2000m.
3. Earthquake intensity: not more than 8 degree.
4. Wind pressure:≤700pa.
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
6. Relative humidity: Daily averages ≤95%, Monthly average≤90%.
1. Load breaker switch adapts double fracture, rotary movable contact structure, with the following three kinds of operating states: closing,opening,earthing.
2. Using SF6 gas as an arc extinguishing and insulating medium, the main circuit seals by the upper and lower housing pouring epoxy resin, the conductive function is unaffected by external influences.
3. Good safety performance. If internal arcing occurs, the housing has an internal structure weak point, it will be rushed to open, followed by the cabinet above the shutter release arc red open air overpressure stream-oriented outside the cabinet, ensure that the switch cabinet security checks.
4. Load breaker switch sets gates, opening, earthing switch three at one, filled with SF6 gas encapsulated in epoxy resin housing, three-position interlock,compact structure,high security and reliability.
5. Small size, light weight, maintenance-free, easy and safe to operate.
