Product Description

The 35kV series oil-immersed distribution transformers produced by Xinte have the characteristics of low loss, low noise, low temperature rise, high reliability, core-hanging free, and no oil leakage. The product adopts advanced design software to carry out electromagnetic calculation, through analysis of the transformer's main and longitudinal insulation, impulse voltage gradient distribution, end electric field distribution, short-circuit thermal stability and dynamic stability strength by computer to ensure the transformer's design margin, so as to ensure the safe and reliable operation of the transformer. 

Features

1. The transformer adopts the core seven-stage temperature control technology;
2. The transformer body adopts a mixed insulation system and high quality parts to achieve the same life design for 30 years.
3. Low noise: the noise is reduced by 3 to 5 decibels than the national standard;
4. No leakage: all seals are made of acrylic one-time molded parts, and fluorescent, positive pressure and negative pressure leak test are used;
5. High reliability:The transformer is equipped with an oil level thermometer, a pressure relief valve with a contact is installed on the top of the oil tank, the oil level indicator of the oil storage tank adopts an oil level gauge with a contact, and the high and low pressure bushing adopts anti-fouling reinforced pure porcelain oil bushing, which can be used for heavy pollution level environment.
6. High-quality insulating skeleton support inside the coilThe inside of the coil is supported by a high-quality insulating skeleton. All coils use internal and external braces, all braces and pads are chamfered, the electric field is uniform, and the reliability is enhanced. All the fasteners on the body of the coil axis adopt self-locking lock nuts, so that the product can withstand long-distance transportation bumps without loosening and without hanging core.
