It is large and medium-sized equipment, dimension of clamping plate is 800 x 800mm, lengthof upper and lower core-pulling stroke can be determined according to the product (it needs lower core-pulling foundation pit when the lower core
pulling exceeds 300mm).
It is mainly used for transformer, 12KV-1250A, 3150A insulating cylinder, contact box, 40.5KV bushing, bending plate,upper and lower shell of SF6 insulating cover, etc.
The composition of the APG Claming Machine:The main machine+Mixing device(three sets)+ Stirring rack+Hydraulic Oil Pump+ Power distribution cabinet.
Automatic pressure Gelation Process
APG process (Automatic Pressure Gelation Process referred to as the APG process) was first filed a patent on June 19, 1969 by Ciba-Geigy, Switzerland. In China, with the development of pressure gelation equipment and its continuous improvement under the Coal Research Institute, as well as the gap between local epoxy resin specialized for pressure gel and imported material increasingly narrow, pressure gelation process in the electrical insulation industry has also been expanded, and has played an irreplaceable role. Pressure gelation technology is now successfully used in the production of high quality enclosed pole, cross-fluorinated sulfur load switch housing, transformers and other products.
Pressure gel process to produce the insulators as outlined below:
1. Material pretreatment
A certain percentage of epoxy resin speical for pressure gel, curing agent, fillers, colorants join the mixing tank. Stir 1 to 2 hours to mix material evenly and no bubbles in the sealed pot under a vacuum state (absolute pressure is less than 500Pa).
Pretreated epoxy resin mixture is injected into the APG mold preheating to 140deg with the help of compressed air or pressurized pump. The mixture is released from the mold after thermal gel forming and get semi-finished products.
APG mold should be set aside suitable gap in a specific parting line surface in order to discharge the air from the mold in the process of injecting material. After the gel injecting into the mold, the epoxy resin due to rapid heating fill into the small gap, leaving the mold in a sealed state, so the material within the mold under pressure gradually gel to get a close texture product. In order to make the mold parting line surface leaving some gap not only able to exhaust but also reliable seal, which require higher accuracy of the mold, especially for some of the complex structure of the insulators, the mold is with much higher accuracy requirements. In short, Pressure gel mold is equipped with a high technical content.
After injection, the products are transferred to the oven, and the finished products get dense and low internal stress after slow cooling under constant temperature of 140deg 10 hours.
This company produces the APG equipment has the following several advantages:
1.The biggest&only manufacturer at the same time do the APG Clamping Machine and APG Mould in china so that make the machine with the mold better coordination which ensure that product qualification.
2. The only company have product testing room in china,if necessary you can stay in our factory test output products(through the dielectric strength testing--the impact testing--the bending testing--partial discharge testing) until being qualified&higher quality and ready to shipment.
3.CE,ISO,SGS certificate and standards,owns many patents and independent intellectual property rights.
4.We can customize machine according to customer's needs.
5. Have 23 year's experience of electric products production technology engineers to your company provide free technology training and help customers make the qualified products.
6. Have rich experience engineer to be responsible for new equipment storting to installation debugging and training.
7.Well equipped with complete facilities and more than 200 skilled workers and operates round the clock on three shifts,so we can keep the orders completed punctually!
8. Specially designed for transformer of thin film degassing and cycle heating system mixing device, greatly improving the uniformity of mixing and pumping vacuum material.
9.Combination of equipment, moulds, as well as under the engineers constantly summarize and improve the production equipment has superior performance,high efficiency energy saving etc.
10.By APG pressure gel molding process, greatly improving the production efficiency, increased the product surface bright and clean degree, reduce the mold cost, reduces the labor costs of inputs.
11.One-stop services for electric factory,we are manufacturer APG Clamping Machine,APG Mould,Oven for APG Processing,Winding Machine for CT&PT,Foil Winding Machine for Transformer,Laser Marking Machine can marking all kinds of materials,like epoxy resin.
