Expandable Winding Mandrel, Transformer Production, Wrapping Mandrel
Basic Info.











We have obtained more than 50 patents. We designed and manufactured many large types of equipment, which run safely and stability, for large-scale transformer production enterprises and insulation processing companies-National Grid, Southern Power Grid, Xining Power Grid, TBEA Shenyang, Baoding Tianwei Group, Qinhuangdao Transformer, XD Group, Jinan Siemens, Hefei ABB, Shandong Dachi, Changzhou XD, Shandong Taikai Group, Xinjiang TBEA, Hengyang TBEA, Yunnan Transformer Factory, Shandong Electric Equipment Factory, Wuxi Putian Iron Core, Wuhan Weideman, Weifang Hui Sheng and many other famous factories.
We hired a senior technology engineer of the famous transformer manufacturer in China as a technical advisor to our company. All products use noted software optimization design, and important product components are based on the finite element analysis of internationally renowned three-dimensional software on the basis of scientific calculations to ensure the safety and reliability of products.
Our company insists on "Products are like people, do a good person in advance" business principles, has won the favor of our customers with reasonable price and reliable quality. We have always believed that
" Only create value for you to reflect our value"
Always be honest, never lie to customers and declear anythings that we do not have

Product Description
It is mainly composed of the cage, sliding sleeve assembly, strut assembly, basic brace, additional brace, transmission part and right angle limiter. The adjustable mandrel has a novel structure, large diameter adjustment range and no damage to the coil during demoulding. The diameter deviation of any two points of the winding mandrel is ≤ 1.5mm, and the cylindricity is ≤ 1.5mm. With the use of the company's winding machine, the effect is better.
