China Suppliers Semi-Conductive Non-Woven Tape for Cables – High Strength, Heat Resistant, and Electric Field Shielding Factory
Product Description
Semi conductive non-woven tape for cables is a special material widely used in cable manufacturing, which has unique electrical and physical properties and can meet the performance requirements of cables under various working conditions. The following is a brief introduction to the use of semi conductive non-woven fabric tape for cables:
1. Product Features
Semi conductive non-woven fabric tape used for cables has semiconductive properties, low electrical resistivity, and can play a role in uniform electric field and reducing electric field stress in cable structures, thereby improving the electrical resistance of cables.
The non-woven fabric substrate has been thoroughly combed and processed, resulting in a semi conductive non-woven tape with high longitudinal and tensile strength, which can withstand the mechanical stress of cables during manufacturing and installation.
Due to the immersion of semiconducting adhesive and drying molding, the resistance value of the semiconducting non-woven tape is relatively small, which helps to distribute and regulate the electric field inside the cable.
The product has good heat resistance and can maintain stable electrical and physical properties in high temperature environments, ensuring the safe operation of cables under high temperature conditions.
Semi conductive non-woven fabric tape is easy to cut, wrap, and longitudinally wrap, and can be conveniently applied in cable manufacturing and maintenance processes.
2. Application method
3. Technical indicators
The technical indicators of semi conductive non-woven tape for cables usually include product specifications, basis weight, tensile strength, elongation, surface resistance, volume resistance, instantaneous stability, long-term stability, etc. The specific values may vary depending on the product model and manufacturer. Generally speaking, products have high tensile strength, moderate elongation, low electrical resistance, and good heat resistance and stability.
4. Color and packaging
The semi conductive non-woven tape used for cables is usually black because black can absorb more heat and reduce light reflection, which helps improve the heat resistance of the product. In terms of packaging, semi conductive non-woven tapes are generally packaged in cardboard boxes for easy transportation and storage.
