Product category: Product Center dry type transformer series product description: Nomex Paper Insulation, environmental protection, safety, reliability and environmental protection; Low noise, maintenance free; Strong overload capacity, high temperature resistance. DuPont leilitong transformer core technology. Product details performance features: better electrical and mechanical properties SG (b) 10 is an insulation system based on DuPont Nomex Paper. Good electrical and mechanical properties are maintained throughout the service life of the transformer. Nomex is not easy to aging, anti shrinkage agent, anti compression and strong elasticity, so it can ensure that the coil of the transformer remains tight even after several years of use, and can withstand the pressure of short circuit. High safety SG10 transformer has no combustible resin, can not support combustion, can be flame retardant, will not explode and release toxic gases, will not cause harm to the environment, other equipment and human body, and is not sensitive to humidity, dust and pollution; There is no possibility of partial discharge and crack in operation. High reliability, high and low voltage coils are made of Nomex insulation material, and impregnated with H-class solventless impregnating paint by VPI vacuum pressure equipment for many times, and cured by high temperature baking for many times. The product is grade H (180 ℃), and the main insulating material is grade C (220 ℃), with strong overload capacity and good short circuit resistance. Under the condition of good ventilation, 20% overload operation is allowed. After the service life of energy-saving and environmental protection products is over, steel, iron and other materials are easy to recycle; All Nomex Paper will not release toxic substances when burned; Other insulating materials can degrade and do not pollute the environment; The product has low loss and energy saving; Low noise and flexible design. The iron core is made of 0.3mm thick silicon steel sheet with high magnetic conductivity, 45 degree full inclined three-stage lap joint, no punching and no pulling screw, and the surface is coated with insulating paint, which is moisture-proof, rust proof, low loss and low noise. High voltage coil high voltage coil adopts continuous structure with high mechanical strength and good heat dissipation conditions, which avoids the disadvantages of high interlayer voltage, poor heat dissipation capacity, easy thermal breakdown and low mechanical strength of multi-layer cylindrical coil, thus improving the reliability of product operation; Excellent moisture-proof performance, more able to withstand thermal shock, never crack, partial discharge less than 5pc, easy to decompose and recycle after life, protect the environment. Low voltage coil the low voltage coil adopts foil type or longitudinal airway high current spiral structure. SG10 products of low-pressure longitudinal airway high current spiral structure coil technology is advanced. The advanced detection, test and temperature control system carries out strict test and inspection according to the national standard before leaving the factory, and the partial discharge test is listed as the factory test item. The advanced dry-type transformer temperature controller is used in the temperature measuring device, which reflects the temperature of the winding through the change of the resistance value of the platinum thermistor embedded in the three-phase low-voltage winding. Integrate specific temperature, with over temperature alarm, over temperature trip, three-phase temperature circuit display and other functions.
