卷铁芯全密封型配电变压器,是近几年研制的新一代低噪声、低损耗型变压器,其铁芯无接缝,较大的减少了空载损耗及空载电流,使空载电流降低60%~80%,高低压线圈在铁柱上连续绕制,绕组紧实,同心度好.噪声下降10分贝以上.由于铁芯连续卷绕,充分利用了硅钢片的取向性,使空载损耗降低了20%~30%,是新一代的高科技节能环保产品.
全密封型配电变压器采用不吊芯结构,使油箱内部与外界完全隔离,无储油柜,在变压器运行中的热胀变化由油箱的弹性波纹片胀缩来做补偿,使变压器油和绝缘件与外界空气、水分离,从而减缓了变压器油和绝缘件的老化速度.油箱密封采用高性能的耐油橡胶,可在现场不吊芯检查情况下保证运行20年,减少运行维修成本,有利于一些维修不便的场所.
新S9型三相油浸式变压器采用全国统一设计标准,绝缘结构先进合理,抗短路能力强,其性能达到国际同类产品水平,与S7型产品相比,空载损耗平均下降10.25%,空载电流下降37.7%,负载损耗平均降低22.4%,且结构合理外型美观,可根据用户要求油箱可以是片式和管式散热,是近年来应用最广的节能产品.
SC9系列环氧树脂浇注干式配电变压器和空气绝缘的SG型干式变压器绝缘性能好,抗短路能力强,耐雷电冲击水平高.环氧浇注干式配电变压器高低压线圈都由环氧树脂浇注密封,所采用的环氧树脂性能好,抗裂,耐高温,机械强度高,寿命长.阻燃、防潮、防爆无污染.
产品体积小、噪声低.各绕组在运行中都有温度自动监测和保护报警装置.在强迫风冷时可使额定容量超40%左右.可以广泛应用于高层建筑、车站、机场、码头、地铁、电厂等重要场所的输配电系统中.
组合式配电变压器（美式箱变）是一种集变压器器身、开关、熔断器、分接开关及相应的辅助设备于一体的变压器.它用全绝缘、全密封结构,并采用双熔丝保护.变压器铁芯采用特殊结构,损耗低、噪声小,箱体不发热,防雷性能好.高压进线采用肘型电缆接头,可操作200A负荷电流,在紧急情况下可做负荷开关操作,具有隔离开关特点.组合式变压器结构紧凑,体积小,占地面积小,投资少,便于安装,可广泛用于机场、高层建筑、商业中心、居民小区、街道等地方,可深入负荷中心安装.组合式变压器定货时请注明终端型或环网型.
SZ型有载调压电力变压器,在使用过程中对节约型有载调压变压器质量可靠,经济指标合理,符合国家GB1094-1996《电力变压器》和GB/T6451-1999《三相油浸式电力变压器技术参数和要求》.铁芯采用优质硅钢片、生产工艺先进；绕组和油道结构设计合理,机械强度高和抗短路能力强,外型美观大方.

Roll the sealed type distribution transformer core is developed in recent years, the new generation of low noise, low loss, and its core transformer no juncture, reduce no-load loss and no-load current no-load current, high ~ 80%, 60% lower in iron wire wound on continuous windings, tight, concentricity well. Noise dropped 10 decibels. Due to the continuous winding, iron makes full use of the manufacturing of sexual orientation, no-load loss reduced by 20% ~ 30%, is a new generation of high-tech energy-saving and environmental protection products.
The sealed type distribution transformer USES don't hang core structure, make internal and external tank completely isolated, no storage cabinets, the thermal changes in transformer tank operation by elastic corrugated chips to make compensation for expansion, transformer oil and insulation parts with outside air, water, and the separation of transformer oil and slow the aging in insulation parts. Seal of high fuel oil resistant balata, but not in the circumstance that hang core inspection operation for 20 years, reduce operation maintenance cost, be helpful for the inconvenience. Some maintenance
The new type S9 oil-immersed three-phases transformer USES unified design standards, advanced and reasonable structure, insulation resistance short-circuit capacity is strong, its performance achieved the international similar product level, with S7 products, on average, no-load loss dropped by 10.25% no-load current decline 37.7%, load loss and lower average 22.4% appearance, reasonable structure according to user's chip and tank can tubular radiator, in recent years is one of the most widely used energy saving products.
Developed SC9 series of epoxy resin casting dry-type power transformer and air insulated SG type dry type transformer insulation resistance short-circuit capacity, good performance, high impact resistance level of lightning. Epoxy resin casting dry-type distribution transformer winding high by epoxy resin casting seal, adoption of epoxy resin performance is good, crack, high temperature resistant, high mechanical strength, long service life. Flame retardant, moistureproof, explosion-proof pollution-free.
Products, small volume, low noise. The winding in the operation of automatic temperature monitoring and are protected alarm device. In the forced air cooling can make the rated capacity over 40%. Can be widely used in high-rise buildings, station, wharf, subway, airport, power transmission and distribution system is the important place.
Combined-type distribution transformer (American box variable) is a new body, transformer switch, fuse, tap-changer and relevant auxiliary equipment in one of the transformer. With all its insulation, seal structure, and adopt double welding wire protection. Transformer core adopts special structure, low consumption, low noise, no heat, lightning case. High-pressure line adopts elbow joint, can operate cable 200A load current, can be done in an emergency operation, load switch with isolation switch features. Combined transformer, compact structure, small volume, cover an area of an area small, less investment, easy to install and can be widely used in airport, high-rise buildings, business center, dweller, streets, can further load center installation. When ordering, please indicate the combined transformer or terminal type ring network.
SZ type power transformer on-load changer, in use process for saving transformer on-load changer with reliable quality, reasonable, accord with national economic indicators GB1094-1996 power transformer and GB/T6451-1999 "three-phase oil-immersed transformer, electric technical parameters and requirements. Core adopts the high quality manufacturing, advanced production technology, Oil and winding road structural design is reasonable, high mechanical strength and resistance short-circuit capacity is strong, beautiful generous.
