​ Polyimide film mica tape is a high-performance insulation material composed of powder mica paper as the insulation main body and polyimide (PI) film as the reinforcement layer composite. It combines the excellent high temperature resistance and fire-resistant insulation properties of mica with the high mechanical strength, corona resistance, and temperature resistance advantages of PI film; Compared with glass fiber reinforced mica tape, its tensile, tear resistance, and high-frequency pulse resistance are significantly improved, and it is widely used in variable frequency high-voltage motors, traction equipment, special high-temperature cables, and new energy electrical insulation scenarios.

​Electrical Insulation Filament Adhesive Tape is made of glass fiber/polyester fiber as the substrate and coated with pressure-sensitive adhesive. Its core functions include electrical insulation, mechanical protection, fixed bundling, temperature and wear resistance. It is widely used in motors, transformers, wire harnesses, reactors, and electrical equipment windings.

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.
