Electrical technology&equipement vietnam

Dear friends and customers we pleased to announced our participation in the 12th International Exhibition of electrical technology and electrical equipment in the City of Ho Chi Minh from 17th to 20th of July 2019. If you want to get more about electric insulation material, please visit us at booth # 23. Venue: Saigon exhibition and convention center (Convention); 799 Nguyen Van Linh, District 7, District 7, Ho Chi Minh City.

2018 Seoul International Electric Fair (SIEF)Invitation

Nantong Rizhi Electric Power Material Co.,Ltd will attend 2018 Seoul International Electric Fair (SIEF). Time: 10th to 12th Oct. Booth no.: H119. Add:COEX exhibition center,Seoul,Korea. It will be a great pleasure to meet every friends at the exhibition.

The effects of the glue colour on the DDP to the insulating material

In fact,about all customers in China choose the DDP with colourless glue.But most foreigh customers choose the DDP with red glue or orange colour. The DDP with red or orange colour glue seems more beautiful,and the glue point is more clear.It’s also easy for us to produce,just need to add a little toner in the glue,no big influence for the cost.But,you forget the property of dielectric loss of the paper.And the dielectric loss will change the electrical strength.So we don’t suggest customers use the DDP with colourful glue.

The effects of electric strength performance of insulation material

Electrical strength is an important factor influencing the performances of insulation materials. And, in the use of electric intensity on its quality and performance is also bigger. And dielectric strength will be influenced by external factors such as environment: 1.Electric strength is affected by humidity and temperature, temperature and humidity is bigger, the dielectric strength is reduced, the opposite is strong. 2.If used in insulating materials, machinery is damaged, can also reduce the dielectric strength of the material, so the protective measures is to handle protection and control of mechanical equipment, to minimize the damage to the machine as far as possible, it can also enhance the insulation performance. 3.The thickness of the material also has effect on the strength of electric, because the material is thicker, cooling, etc. The effect not beautiful, so electric strength is low, thus the performance of the insulation material is also reduced.
