Electrical Insulation Semiconductor Crepe Paper, modified with carbon black conductivity on the substrate of electrical corrugated paper, has controllable weak conductivity (semiconductor properties), while retaining the characteristics of stretchability, resistance to transformer oil, and good flexibility of corrugated paper; The core function is to evenly distribute voltage, alleviate electric fields, suppress partial discharge, and prevent corona. It is mainly used for internal insulation shielding of high-voltage transmission and transformation equipment, which is different from ordinary insulation corrugated paper.

Electrical Insulation Aramid Board is a hard board formed by hot pressing aramid fibers (mainly meta aramid). It has a long-term temperature resistance of 210-220 ℃ (H/S level heat resistance), high voltage resistance, self extinguishing flame retardant, vibration resistance, and high temperature non melting. It also has dual functions of electrical insulation and structural support. It is mainly used in high temperature and high pressure conditions that ordinary epoxy boards and phenolic boards cannot handle.

In the realm of electrical insulation, the choice of materials directly determines the reliability and lifespan of transformers and other high-voltage equipment. The Electrical Insulation Kraft Paper from Hanyao is a fundamental component in transformer insulation systems, offering a proven combination of mechanical strength, dielectric integrity, and thermal stability. Manufactured from 100% high-purity wood pulp, this paper provides superior performance even under demanding conditions. With thickness options ranging from 80μm to 170μm and compliance with A-class insulation standards (105°C), it plays a vital role in coil insulation, cable wrapping, and other critical electrical applications. This article examines the product's specifications, key features, and the manufacturing quality that makes it a reliable choice for transformer and motor manufacturers worldwide.

PVC Coated Fiberglass Sleeve is woven from alkali-free fiberglass and externally coated with PVC resin. It combines the high tensile strength of fiberglass fabric with the chemical resistance of PVC material.

In the world of electrical insulation, the choice of material can mean the difference between reliable operation and catastrophic failure—especially in high-voltage motors and generators operating under extreme conditions. The Polyimide Film Mica Tape from Hanyao represents the premium tier of mica-based insulation products. By replacing polyester film with high-performance polyimide film, this tape achieves insulation levels of Class H (180°C) and even Class C (220°C), far exceeding the Class F rating of conventional polyester mica tapes. With excellent dielectric strength, mechanical toughness, and chemical resistance, it is the material of choice for demanding applications in aerospace, defense, and heavy industry. This article examines its technical specifications, key advantages, and the applications where it delivers unmatched reliability.
