S13-3150KVA power transformer is the key sales product for the selection of power transmission and distribution equipment in China, with excellent energy-saving effect. S13-3150KVA power transformer key components: oil tank, coil, core, transformer oil, pressure release valve, gas relay (more than 800KVA transformer belt).

The meaning of the characteristic number of S13-3150KVA power transformer in China is: above S7 type, for every 10% reduction of no-load loss, the number “7” will add “1” to the data. From S7 to S13, the load loss is significantly reduced, taking 400kVA products as an example, the S11 no-load loss is 570W, and the S13 no-load loss is 410W, a decrease of 28%.

S13-3150KVA Power Transformer Product Standard:

1. GB1094.1-2-2007 power transformer

2. GB1094.3-5-2007 power transformer

3. GB/T6451-2008 performance parameters and requirements of three-phase oil-immersed power transformer

4. GB/T10237-1988 Insulation level of power transformer and air gap of insulation outside insulation test

5. JB/T3837-1998 transformer product specification compilation method

Compared with S11 type, the S13-3150KVA power transformer selects new materials, new processes, new structures, optimized design, and carefully manufactured, compared with S11 type, the no-load loss is reduced by 25%, the no-load current is reduced by 35%, and the annual cost is reduced by 10.5%. The core material of S13-3150KVA power transformer is made of high magnetic permeability and low loss high-quality silicon steel sheet, and the structure is a drawing rod clamping stiffness frame structure, with stable performance, low noise and strong anti-short circuit ability. The winding resistance is made of high-quality oxygen-free copper wire, which has good conductivity and low load loss. The body is clamped with high-toughness electrical laminate, all wires are firmly clamped, and the stays and backings are made of high-density insulating cardboard to optimize the electric field distribution of the transformer. The S13-3150KVA power transformer uses corrugated oil tank, which has beautiful appearance and high heat exhaust efficiency. Plateau thickened casing, suitable for high altitudes. This series of transformers has advanced technical performance, green environmental protection, safety and reliability.
