China Suppliers Factory Semi-Conductive Nylon Tape for High-Voltage Cable Wrapping and Shielding
Product Description
Semi conductive nylon tape for cables is a widely used material in cable manufacturing, with unique physical and chemical properties that can meet the requirements of cables in complex environments such as high voltage and high temperature. The following is a detailed introduction to the use of semi conductive nylon tape for cables:
The semi conductive nylon tape for cables is made of nylon based fibers that have undergone special processing and are coated with a semi conductive compound with uniform electrical properties on both sides. This material not only retains the excellent properties of nylon fiber such as high strength, wear resistance, and corrosion resistance, but also has good conductivity and semi conductivity, which can effectively improve the electrical performance of cables.
Nylon fiber itself has high longitudinal strength. After special processing, the strength of the semi conductive nylon tape is further improved, which can meet the requirements of cable use in complex environments.
The semiconductive compound coated on the surface of the semiconductive nylon tape has good conductivity, which can effectively reduce the resistance of the cable and improve the transmission efficiency of the cable.
Nylon material itself has excellent corrosion resistance and can maintain stable performance in harsh environments such as humidity, acidity, and alkalinity.
Semi conductive nylon tape can maintain stable performance at high temperatures, meeting the requirements for cable use in high-temperature environments.
Semi conductive nylon tape has good flexibility and plasticity, making it convenient for winding, tying, and other processing operations during cable manufacturing.
Semi conductive nylon tape for cables is mainly used for conductor winding, core shielding, and binding of high-voltage cross-linked polyethylene cables, high-voltage or ultra high voltage power cables, mining cables, and other cables. In the cable manufacturing process, the semi conductive nylon tape can tightly adhere to the cable conductor and insulation layer, forming a continuous conductive or semi conductive layer, improving the electrical performance and safety of the cable.
The technical indicators of semi conductive nylon tape for cables include thickness, unit weight, tensile strength, elongation at break, surface resistance, volume resistance, etc. The specific values of these indicators may vary depending on the different specifications and uses of the product. Generally speaking, the thickness of semiconducting nylon tape is between 0.10mm and 0.14mm, the unit weight is between 90g/m² and 110g/m², the tensile strength is not less than 100N/cm, the elongation at break is not less than 25%, and the surface resistance and volume resistance are both low.
When using semi conductive nylon tape for cables, the following points should be noted:
- Storage conditions: It should be stored in a dry, ventilated, and non corrosive gas environment, avoiding direct sunlight and rain.
- Handling and transportation: During the handling and transportation process, it is necessary to avoid dropping, throwing, and squeezing heavy objects to prevent damage to the product.
- Pre use inspection: The product should be inspected before use to ensure that there are no quality issues such as damage or contamination.
- Operate according to specifications: During the cable manufacturing process, relevant specifications should be followed to ensure that the semi conductive nylon tape can function correctly and effectively.
