Material Advantage In Vacuum Pressure Impregnating For Electrical Product Insulation

Introduction

Vacuum pressure impregnation equipment is mainly used for insulation treatment of electrical products. For example, insulation materials for high-voltage motors, wind turbines, H-class insulated dry-type transformers, power capacitors, and cables are impregnated. Products such as motors or transformer coils can be dehydrated and degassed during the vacuum stage by vacuum pressure impregnation, reducing the impact of impurities such as water and gas on insulation; In the pressure impregnation stage, the insulation paint can completely penetrate into the interior of the insulation structure under pressure, strengthening the overall insulation, thereby improving the insulation level and improving the electrical performance of the product.

Scope of use

Vacuum pressure impregnation equipment is also used in the materials industry to solve material modification and improve organizational structure, achieving the goal of improving material properties. Precision castings such as graphite products, engine casings, refractory bricks, wood, etc. By vacuum pressure impregnation, the density of graphite is increased, and the strength and resistance characteristics are enhanced; In automotive engine castings and high-pressure valves, vacuum pressure impregnation can completely solve the problem of micro leakage, improve product quality, and eliminate the leakage of the workpiece itself. Refractory bricks and wood can change the characteristics of the substrate to achieve different effects by impregnating with different immersion agents (such as asphalt, preservatives, etc.).

Our impregnating advantages:

WxiJiniu Machinery Co.,ltd. formerly known as Wuxi Metallurgical Machinery Factory, registered trademark for "Jinqiu" brand, was founded in June 1969. It is in Wuxi city, 150 kilometers far from Shanghai city. We have been to stated enterprise, since 2002, we recombined to private company, and got fast development, we are one big group now, our group mainly produces hydraulic press brake, hydraulic shears, coiling feeding line--especially for aluimnum cap making, slitting line, cut to length, transformer machines....and other series product. It is one of the earliest factory in China to make these metal sheet machines.

The company covers an area of 62,000 square meters with 300 people. It has advanced production equipment’s with imported large CNC gantry milling machine, imported large CNC boring and milling machine, 100-ton carriageway and a series of iconic devices. Our excellent design team can make personalized products according to the users’ demands. At the same time, we have established long-term cooperation with some famous university, such as Jiangnan university, Nanjing University, Jiangsu University. Through our research staff innovation and hard work, we have received dozens of patents. At the same time, we have ISO and CE certifications.

In the domestic market, we set up many offices in different cities, Beijing, Kunming, Hefei…And to the international market, in many countries, we have sales and service agent, USA, Peru, Brazil, India, Russia…. Our engineers have been to those countries to install our machines. Because of our machine good quality and good after-sales service, the customers give us very high commend.

We hope to set up very good and long cooperation with more customers around the word.
