The role of wire and cable wrapping tape
1. protect the insulation or inner sheath layer from damage to the armor when the cable is armored, and play the role of buffer and liner.
2. in the process of cable use, due to different materials on the cable insulation or inner sheath layer from heat insulation, or anti-corrosion, anti-aging and other different effects.
3. make the wire into a cylindrical shape to prevent the wire from loosening.
4. shielding, so that the signal is not disturbed.
The 5. acts as an insulation between the conductor and the shield wire.
Wire and cable wrapping tape material
1. Aluminum foil Myla
There are single-sided hot melt self-adhesive and double-sided hot melt self-adhesive, generally single-sided, small shielding area, large shielding resistance.
bag with two ways:
Aluminum foil inward, used in no wire no longer through the preparation or winding of the wire occasions, also play a shielding role, aluminum foil outward, aluminum foil relative to copper foil, aluminum foil is soft and cheap, so the use of particularly wide.
2. Myrasa Belt
Also known as polyester belt, has good tensile strength, has the effect of preventing loose,
3.PTFE tape
It can also be called polyvinyl fluoride cable wrapping tape. This product is prepared by polytetrafluoroethylene dispersion resin and has a special fibrous microporous structure. The product has low relative density, low dielectric loss and is affected by temperature and signal frequency changes. Small, stable dielectric constant, excellent temperature resistance, good weather resistance, etc. It is a very ideal high-frequency wire and cable dielectric material.

Application of synthetic mica tape in fire-resistant cable
The application field of fire-resistant cable is gradually expanding, from the original offshore oil platform to aviation, aerospace, navigation, subway, tunnel, commercial building, hospital, dance hall, metallurgy, chemical industry and power plant, etc., which require high fire resistance rating. In recent years, with the maturity of the manufacturing technology of fire-resistant synthetic mica tape, the amount of fire-resistant cables manufactured with it is increasing. As we all know, the refractory mica tape is divided into two categories: *(950-1000 ℃) and B (750-800 ℃).
Refractory mica tape-Refractory insulation
High temperature resistance: synthetic mica belt fluorine gold mica belt, does not contain crystal water, melting point 1375 ℃, safety margin, high temperature resistance is the best, phlogopite releases crystal water above 800 ℃, high temperature resistance is the second, muscovite releases crystal water at 600 ℃, high temperature resistance is poor.
Calculation method of used quantity of polyethylene heat shrinkable winding tape
Heat shrinkable tape (open sleeve) is used to prevent corrosion at the welding place of two steel pipes. What is important is to use a set of heat shrinkable tape for one joint joint. The specifications are divided according to the pipe diameter and the price is sold according to one set. Therefore, a set of heat shrinkable tape will contain all the materials required for this weld joint corrosion protection: main tape; Epoxy primer; Fixing sheet; Adhesive tape.

Flame retardant cable is characterized by delaying the spread of flame along the cable so that the fire does not expand. Whether it is a single cable or a bundle of laying conditions, the cable is known to burn when the spread of the flame can be controlled within a certain range, so you can avoid the fire caused by the major disasters, thereby improving the fire level of the cable line.
What is halogen-free flame retardant belt?
Halogen-free flame retardant products with flame retardant level up to UL94-V0 standards, does not contain fluorine, chlorine, bromine, iodine halogen. Low smoke when burning, more environmentally friendly. The product has good self-adhesion, completely self-melting in a short time, no layering, and good sealing. The self-adhesive tape has good ductility, insulation and excellent physical properties.
