Cable Semi-conductive Non-woven Tape

1、Product Features

Semiconductority: 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.

High strength: 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.

Low resistance: 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.

Good heat resistance: 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.

Easy to process: 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.

Conductor shielding: 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.

Outer binding and isolation of insulated wire core: 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.

Underlay layer and shielding of metal layer: 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.

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.
