Main factors affecting the performance of insulating materials

There are many types of insulating materials. In their use, different environments and different materials are factors that affect the performance of insulating materials. In the use of electrical insulating materials, the most important factor is electrical. The size of the intensity. Special attention is required: 1. If the insulation material is damaged due to the mechanical use itself, the performance of the insulation material may be degraded. Therefore, while processing the material, care should be taken to minimize the…

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…

Electrician insulation crepe paper tube

The electrical insulation crepe paper tube is made of crepe paper and is suitable for use as an insulating material in motors and capacitors, especially in oil-immersed transformers. Advantages of transformer crepe paper tube: 1. Inherent dielectric strength Insulated crepe paper tubes produced by ZTELEC have a lower dielectric constant, resulting in a more uniform electric field distribution between the insulation and the cooling medium. 2, thermal stability The product has a UL material temperature rating of 220 degrees, which…

Non-electrical technical indicators of FR4 CCL

FR4 CCL quality directly affects the quality of printed boards. The main non-electrical technical standards for measuring the quality of CCL are as follows: Anti-stripping strength The peel strength is the minimum force required to peel the substrate from the copper foil per unit width, and the unit is kg/cm. Use this indicator to measure the bond strength between the copper foil and the substrate. 2. Warpage Warpage refers to the warpage value per unit length, which is a measure…

How to extend the life of high-density Insulation Compressed Pressboard

How to extend the life of high-density Insulation Compressed Pressboard, ZTELEC offers you 5 tips: 1. Prevent high-density insulating paperboard from being exposed to high temperatures, as the compressed pressboard life will be halved for every 8 °C increase in ambient temperature. 2. Avoid light and radiation, because light and radiation will change the molecular structure of the insulation board and reduce the insulation strength; 3. Avoid contact with corrosive chemical gases or liquids, as these will denature the insulation…
