Separates live parts at different potentials to prevent current leakage and short circuits.

Classification and Properties of High-Temperature Insulation Materials

Electrical insulation materials can be categorized based on various criteria such as physical state, thermal class, and voltage rating; materials with

This constitutes the largest share. For leading listed companies, this typically ranges from 50% to 77%; specific examples include Dongcai Technology

Electrical insulation materials encompass a wide range of products, each with distinct manufacturing processes.

Very low cost with stable insulation properties; widely used for insulation gaps in overhead transmission lines and conventional switchgear.

Structural behavior within the normal operating temperature range

The core structural characteristics of high-temperature resistant plastics involve molecular-level designs—such as rigid backbones, high-bond-energy c

Selecting high-temperature resistant plastics requires a comprehensive evaluation based on multiple core criteria—including thermal, mechanical, and e

Various types can be used long-term within the 150°C–300°C range; certain specialty materials (such as PI) can withstand decomposition temperatures up

High-temperature resistant plastics are a class of polymer materials capable of maintaining physical and chemical stability in high-temperature enviro
