High-temperature lines have characteristics such as high temperature resistance, corrosion resistance, aging resistance, and weather resistance. To reach these general requirements of quality, many data combinations are processed by special techniques. In production, in addition to the primary data, supporting information is also necessary.
1. Fill data include: polyester fiber, cotton yarn, PP rope. The intention is to insist on rounding the cable, reduce the amount of rubber, reduce costs, and increase cable strength. Among them, polyester fibers are commonly used for wire rods with a high demand for twists and turns.
2. Separated materials, including: cotton paper, polyester tape, foam PP tape, talc/mica powder, silicone oil, DOP, B.T.A.
(1) Core cotton paper, polyester tape, and foam PP tape. When the cable is cabled, it can wrap the paper tape to make the wire round and ensure the opening of the paper.
(2) When talcum powder/mica powder is extruded from the outside, the PVC of the core wire is coated with coated PVC to be heated, and it is simply adhered and separated with talcum powder/mica powder to ensure peeling and control of adhesion. High temperature and fireproof cable
(3) Silicone oil, spraying during insulation extrusion, the first is to improve the adhesion between the conductor and the insulation, for insulation between the high temperature cable and the outer cover to ensure open skin.
(4) DOP, used between conductor and insulation to improve the adhesion between conductor and insulation.
(5) B.T.A., the solution is applied to the outer surface of the conductor during the insulation of the extrusion. The primary role is to avoid oxidation of the bare copper wire.
