Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of insulators, it is recommended to match specific application scenarios based on key technical parameters such as voltage level and temperature resistance range. For example, there is a significant difference in the dielectric strength requirements for materials between high-voltage transmission and distribution equipment and electronic components.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support, especially for the procurement of industrial grade insulators with long-term stable supply.
  • In the power system renovation project, the mechanical strength and weather resistance of the insulator need to be adapted to the outdoor environment, while considering the UV protection requirements of different climate regions.
  • For high-frequency electronic device applications, it is recommended to pay attention to the dielectric loss parameter test reports provided by suppliers and evaluate their technical reliability in conjunction with industry data.

Knowledge Base

Q

Optical instruments: Lens insulators have high optical transparency and insulation properties, and are commonly used to manufacture high-definition lenses, such as lenses in microscopes, telescopes, cameras, and other optical instruments. Camera: Lens insulators are also widely used in camera manufacturing, such as security monitoring cameras, smartphone cameras, etc.

Q

Computer cable insulation refers to the material wrapped around the outer layer of the cable conductor, whose main function is to isolate the conductor from the external environment, prevent current leakage and external factors from damaging the cable. The material and performance of computer cable insulators have a significant impact on the electrical performance and service life of cables. Common insulation materials for computer cables include polyvinyl chloride (PVC)
