PVC insulated power cable is suitable for laying fixed in power transmission and distribution lines with A.C. 50HZ and rated voltage of 0.6/1kV.
XLPE insulated power cable has a number of advantages compared with paper insulated and PVC insulated cables. XLPE cable has high electric property, mechanical property, heat aging performance, environmental stress crack resistance, chemical corrosion resistance, and it also has simple structure, convenient operation and it is not restricted by laying in large difference of level. It can be applied in high temperature of 90 degree for a long time.

Brand Endorsement: Dongfeng Cummins, as a joint venture brand, boasts mature engine technology, comprehensive global warranty service, and high parts interchangeability.
Compact Structure: Compared to higher-powered models, the JHK-24GF is compact and lightweight, facilitating transportation, installation, and relocation.
Easy Maintenance: Designed with ease of maintenance in mind, the filter and oil filler are conveniently located, simplifying routine maintenance.
Strong Environmental Adaptability: Capable of stable starting in ambient temperatures ranging from -15°C to 40°C (equipped with a preheating device), suitable for various climatic conditions.

This transformer feed a diode rectifier, 6 phase, 12 pulses, which feeds the load with DC voltage 750v, the rectifier is not equipped with smoothing or interphase coil on 750v side, we are responsible of the compatibility of the transformer-rectifier system. The K factor of the transformer is K13, which means the transformer is operating in a heavy harmonic environmental, which is considered by us during design. The transformer is working 20/24 hour, 365 days at -35 to +40 ℃ and 100% humidity. The transformer is able to work at 150% of the rated power with peak of 300% for 20seconds due to peak of voltage every 3 minute without exceeding the temperature of 100℃,the temperature rise is 80℃ max at rated power, the insulation of the copper winding is adopt NOMEX with class H(220℃)

The rated power of the transformer is 750 kVA with ONAN cooling. The primary voltage is 13.8kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.4kV, they formed a vector group of Dyn11.

The 5000kVA transformers will each be supplying 3x compressors with 790kW motors which are started Direct-on-Line (D.O.L). The intention is for the 5000kVA transformer to accommodate 2x 790kW motors starting simultaneously D.O.L with the third starting some time after.The HV and LV cables are bottom entry, an 800 * 400mm opening is provided on the bottom of the enclosure for HV cable incoming, an 400*400mm opening is provided on the bottom of enclosure for LV cable incoming. Which is sealed with temporary low-carbon steel plate.The shock proof rubber pad is installed at the bottom of the transformer, which has excellent isolation effect and can reduce the impact of live load and seismic force on the transformer. There are three surge arresters installed on the enclosure and connected to the each phase of HV terminal.The transformer is equipped with no load tap changer, the tapping range is ±2*2.5% at primary side.The cooling is AN,but client is request to add additional fans，which means can add the capacity of transformer. The connect group is Dyn11.

The rated power of the transformer is 200 kVA with ONAN cooling, the primary voltage is 0.525/0.55 kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.38 kV, they formed a vector group of Yyn0.

These substation step down transformers were designed with ABB OLTC and equipped with AVR.
