China Suppliers Factory Semi-Conductive Tetoron Tape for High-Voltage Cable Wrapping and Shielding
This type of tape has uniform semiconductive properties, which can provide effective electric field control in cable structures, reduce electric field concentration, and improve the electrical safety performance of cables.
In addition to the semiconductive layer, the Teflon tape also includes an insulation layer to protect the interior of the cable from external environmental influences and ensure long-term stable operation of the cable.
Tetoron tapes can usually maintain stable electrical and physical properties at high temperatures, meeting the requirements for cable use in high-temperature environments.
It can be easily cut, wrapped, and fixed according to the needs of cable design, improving the efficiency and accuracy of cable manufacturing.
Select the appropriate semi conductive Teflon tape material according to the specific requirements of the cable, ensuring that its electrical, heat resistance, and mechanical properties meet the requirements.
In the cable manufacturing process, it is necessary to strictly control the process parameters such as winding tension and overlap rate of the Teflon tape to ensure the uniformity and continuity of the semiconducting layer.
Conduct strict electrical and physical performance tests on the produced cables to ensure that the semi conductive Teflon tape plays its due role in the cables.
Tetoron belts should be stored in a dry, ventilated, and non corrosive gas environment, avoiding direct sunlight and rain. During transportation, care should be taken to avoid dropping, throwing, and squeezing heavy objects to prevent damage to the product.

Semi conductive Teflon tape is mainly used to improve electrical and insulation performance. It provides uniform semiconductive properties that control the electric field in cable structures, reduce electric field concentration, and enhance the electrical safety of cables.
It is primarily applied in the manufacturing of high-voltage and ultra-high-voltage power cables. Specifically, it is used in conductor shielding, insulation shielding, and the semi-conductive layers to optimize electrical structure and reduce partial discharge.
The tape offers high heat resistance, allowing it to maintain stable electrical and physical properties at high temperatures. It has a short-term stability limit of up to 230°C and long-term stability of up to 145°C.
During cable manufacturing, it is critical to strictly control process parameters such as winding tension and the overlap rate of the Teflon tape. This ensures the uniformity and continuity of the semiconducting layer.
The tape should be stored in a dry, ventilated, and non-corrosive gas environment, protected from direct sunlight and rain. During transit, handle with care to avoid dropping, throwing, or squeezing under heavy objects to prevent physical damage.
