Product Description
Company profile of Tengde group.
Jiangxi Tengde Industrial Co., Ltd. owned more than five industrial companies, the production workshops mainly located in Jiangxi Province of China, the total area is about 200,000 square meters, which has been engaged in the R&D, production, and sales of insulating materials, electrical materials and other products. Tengde and all of its subsidiaries have obtained ISO9001:2015 international quality system certification, ISO14001 environmental system certification, Occupational Health and Safety Management System Certification, UL certification and a number of utility models and national invention patents. Main products include: Class H dry-type transformer casting resin, indoor and outdoor transformer resin, insulation resin, iron core paint resin, room temperature resin, mold release agent, etc. At present, the products account for 50% of the domestic sales, and offices are set up in China and other countries. In the future, the company will reach deeper cooperation with well-known domestic enterprises as JST, Siemens, etc. It is expected that dry-type transformer and transformer resin market will occupy 75% of the domestic market share, and continue to expand overseas market, such as: Germany, Russia, Dubai, and the year-on-year sales growth is 20%. The company has reached the target of annual output value of 600 million. To meet the needs of enterprise development, ensure the core competitiveness of the company, improve product performance, 10 million has been invested to build a R & D center with the area of 2116 square meters, including more than 20 members with the title of doctor, master, senior engineer, intermediate or above professional titles, and a multi-disciplinary organic complementary, professional R & D team is established.

Alicyclic, prefilled , thermally-cured and two-component epoxy casting resin system for outdoor application.
Applications
Outdoor electrical insulation material for medium and high voltage
application, such as current and voltage transformers ... Etc.
Conventional casting with stage-wise curing, or pressure gelation or automatic pressure gelation casting (PG or APG process).
Properties:
▪ Good mechanical and electrical properties;
▪ Good thermal shock resistance;
▪ Resistance to corrosion caused by ultraviolet radiation;
▪ Suitable for manufacturing of insulators with good weathering resistance
and capability of operation under harsh conditions.
▪ Use of filler subject to treatment with silane coupling agent, improving
the dielectric properties under wet conditions;
Viscosity increase and gel time at various temperatures, refer to Figs: 4.1 and Fig 4.2.
