High Density Polyethylene Sheets

High Density Polyethylene Sheets. Chinese name: Polyethylene plate. PE sheet is a high crystallinity, non-polar thermoplastic resin. The original HDPE has a milky white appearance and a semi-transparent shape in a thin section. PE sheet product features: 1. The wear resistance of high molecular weight polyethylene board is the first in plastics, and the higher the molecular weight, the higher the wear resistance and impact resistance of the material; 2. The impact strength of ultra-high molecular polyethylene sheets is the…

Crepe paper for transformers

Crepe paper for transformers is made by wrinkling of electrical insulation paper. There are crepe along its lateral direction, and the crepe are pulled apart when stretched. Crepe paper with different elongation can be produced due to different wrinkle processing procedures. The thickness of the insulating paper is generally 0.05 mm to 0.12 mm, and the elongation is in the range of 5% to 200%. Insulating crepe paper is often used for the winding insulation of oil-immersed transformers, such as…

SMC insulation board

ZTELEC successfully developed the SMC insulation board of 1M×2M specification (thickness 3-28mm) according to the requirements of “SMC unsaturated polyester insulation separator applied to high voltage electrical switch instead of 3204 epoxy resin board” proposed by the product conference. The arc resistance and hygroscopicity are far better than the epoxy insulation board, which greatly enhances the insulation of the high voltage cabinet, ensuring the safety and reliability of the high voltage cabinet. SMC insulation board product characteristics: high mechanical strength,…

FR-4 insulation boards

FR-4 is a code name for a flame resistant material. The resin material must be self-extinguishing after being burned. FR-4 is a commonly used insulating glass fiber board. Unlike ordinary insulating sheets, it can be flame retardant. In addition to good flame retardant properties, its mechanical strength and voltage resistance are also very good. It still has high mechanical strength at normal temperature of 130 ° C, good electrical properties in dry and wet state, flame retardant, used in electrical…
