S11-M Power Transformer Product Description S11-M Electrical Power Distribution Transformer a new generation of low noise and low loss transformer developed in recent years. The reel core fully sealed power distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%. The corrugated oil tank is adopted in the transformer, and the oil conservator is cancelled, the box cover and the box edge are completely welded or fastened by bolts, thus prolonging the service life of transformer oil. The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.

BKXGN-12 Solid Insulated Switchgear Product Description BKXGN-12 Solid Insulated Switchgear is suitable for middle voltage power distribution system with a rated voltage of less than 10kV and a rated current under 1250A. It is more reliable than the SF6 ring main unit, and is more suitable for a wider range of applications. MV Switchgear Feature • No SF6 gas inside, avoiding pressure tank designing. • All live parts are sealed or embedded in the epoxy resin and silicon rubber, fully insulated and wholly enclosed structure, safety protection level: IP67. • All operating mechanism sealed inside a box, truly maintenance-free. • Enhanced phase separation design, independent phase insulation to avoid the fault between phases. •Standard modular design to facilitate unit extension, modification and replacement. • Switch working position of each phase could be observed independently. • Safe, smart, environment-friendly, flexible assembly enabled, good performance to apply in special environments. • Multiple mechanical interlock to achieve 'five-protection' function. • Complete indoor & outdoor application solution. Service environment Coastal area: fully sealed structure of the mechanism, professional high salt spray testing equipment to ensure long-term application in coastal areas. Low temperature area: The solid insulated switchgear doesn't need SF6, so the potential problem caused by insulation gas being liquified under low temperature can be avoided. Plateau area: Due to the absence of SF6, the problems caused by the big pressure difference between the inside and outside of the gas tank in high altitude areas can be avoided. Explosion forbidden places: The switch adopts vacuum interrupter sealed with epoxy resin bushing which can prevent the gas exposure and explosion. Basement with workers: The density of SF6 is 5 times higher than air on the same condition. So if the SF6 in a traditional RMU leaks out, it will accumulate in low area, so the workers there could be harmed or suffocated. Frequent switching operation situation: Switch operations for solid dielectric designed RMU reaches 20,000 times. Areas with high requirements for environmental protection: Our Bokong Electric solid insulated switchgear doesn't contain SF6, which is a kind of greenhouse gas.

Potentiometer is a resistance element that has three leading ends and the resistance value can be adjusted according to a certain change law. A potentiometer usually consists of a resistance body and a removable brush. When the brush moves along the resistance, the resistance value or voltage is obtained at the output which is related to the displacement. The potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor, because its role in the circuit is to obtain and input voltage (applied voltage) into a certain relationship with the output voltage, so called potentiometer.
