Semi-Conductive Non-Woven Tape Supplier in China - High Strength & Heat Resistance | Factory Direct
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:
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.
Application method
In the cable manufacturing process, non-conductive non-woven tape can be used as a conductor shielding layer to improve the electric field distribution inside the cable and prevent the occurrence of partial discharge.
Suitable for the outer layer of cable conductors and insulated wire cores, it plays a role in binding and isolation, protecting the insulation layer from external damage.
Using a semi conductive non-woven fabric tape as a cushion or shielding layer under the metal layer of the cable can further homogenize the electric field and improve the electrical performance of the cable.
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.
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.

Frequently Asked Questions (FAQ)
What is the primary purpose of semi conductive non-woven tape in cable manufacturing?
It is widely used to uniform the electric field, reduce electric field stress, bind and isolate insulated wire cores, and act as a cushioning or shielding layer under metal layers to improve overall electrical performance.
How does the tape improve the electrical properties of cables?
Due to its semiconductive properties and low resistivity, the tape helps evenly distribute electrical stresses inside the cable structure, preventing partial discharge and enhancing electrical resistance.
What is the thermal stability rating of this semi conductive tape?
The tape offers excellent heat resistance, with short-term temperature stability of up to 230°C and long-term stability ranging from 90°C to 110°C, ensuring reliable operation under high-temperature environments.
Why is the cable tape manufactured in black?
The black color is chosen because it absorbs more heat and reduces light reflection, which helps enhance the heat resistance and physical stability of the non-woven tape.
Can I request custom specifications for the tape?
Yes, while standard specification ranges (thicknesses from 0.1mm to 0.35mm) are available, we support customizing other specifications to meet your specific cable structural requirements.
How is this product packaged for transit and storage?
The semi conductive non-woven tapes are packed securely in high-quality cardboard boxes, designed to ensure convenient transport, safe handling, and protection from environmental factors during storage.
