Product synopsis:
SGB10 series the encapsulation H level dry type transformer adopt (Germany) MORA dry type transformer special technology, make product safety and meet to fire waterproof environment protection. It is the ideal product distribution system. Widely used in the subway, ships, mining, chemical, electric power enterprise and personnel intensive buildings etc various security fire prevention have special requirements occasion.
Execution standard:
IEC726-11 "gb electrotechnical commission standard - dry power transformer"
GB4208-1993 the shell protection grade of [IP code]
GB6450-1986 "dry type power transformer"
JB/T10088-1993 the 6 - good 500kV level of transformer
GB/T1028-1997 "dry power transformer technical parameters and requirements"
JB/T56009-1998 "dry type power transformer product quality grading"

Properties:
Insulation: insulation class for H level (180 ℃), insulation design big margins.
Safety: SC (B) 10 series dry type transformer design for H heat insulation class and grade main insulation materials for grade C (heat-resisting ℃) the United States can reach 220 NOMEX paper, transformer dupont will not in use, flame retardant, not companies.the explosion and release harmful gas.
Green: use high magnetic transformer core silicon steel, high quality cold-rolled add special design, operation noise shipped under national standards. Life cycle recycling, after do not pollute the environment.
Wetness resisting sexual: due to the density of the transformer insulation NOMEX paper products in most in damp environment, can still work satisfactorily. When the whole processing coil via multiple vacuum pressure leaching lacquer, make wire sealing level and coil mechanical strength again strengthen and improve the transformer prevent mould and moistureproof sex.
Durability: insulation class H can withstand the 180 ℃ temperature, good heat resistance, high mechanical strength, thermal conditions over load is extremely good, strong ability of self-learning, thermal capacity is also extremely strong, hot struck long service life, from heat bilges cold shrink influence, have good toughness and elasticity, never cracked.
Economic: due to the high temperature resistant properties insulation system, can reduce transformer cooling space, same capacity compared the lower level of transformer insulation, can design structure is more compact, weight reduced. 9 and 10 type transformer type, compared the 10 type no-load loss than nine type transformer also corresponding reduced by 15% and operation cost can be greatly reduced.
