Wire and cable are used to transmit electrical (magnetic) energy, information, and wire products that enable electromagnetic energy conversion. The generalized wire and cable are also referred to as cables. A narrower cable is an insulated cable. It can be defined as: an assembly of the following components; one or more insulated cores, and their respective possible coverings. Protective layer and outer sheath, the cable can also have additional uninsulated conductors.
The power cable is mainly composed of a conductor, (semi) conductor shielding layer, insulation layer, insulation shielding, buffer layer, metal sheath, outer sheath and semi-conductive coating. If the three-core cable will be multi-belt, sheathed armored and so on.
The following are the main package applications:
1.PET tape: It is generally used for cables, communication cables, data cables and other cables, which can strengthen the insulation.
2, refractory mica tape, flame-retardant tape (halogen fiberglass tape), fiberglass tape; special requirements, fire-retardant and fire-resistant;
3.Semi-conductive tape, copper tape, aluminum plastic composite tape --- shield
4.Aluminum tape, non-magnetic steel tape, galvanized steel tape, painted steel tape - reinforced armored
5.Ribbon, identification tape, printing tape, cable tie ------ logo, wrapping
PET tape: Generally used for control cable, communication cables, data cables, etc.
Non-woven fabric: it is a variety of cables into the package
Water blocking tape: Water blocking cable is practical, it can also be used as high voltage power cables
Mica tape: fire-resistant power cable
Low-smoke, halogen-free wrapping tape: Used as a flame-retardant application, especially for environmentally friendly cables, and cables with high flame retardancy
Semi-conductive nylon tape: used as a conductive wrap shield for medium- and high-voltage cross-linked cables, also for low-voltage concentric cables
PP tape: winding pad for armored cable
Asphalt paper tapes: For cables with corrosion protection requirements, generally used for submarine cables
LAP (aluminum-plastic composite tape): for integrated waterproof layer, common in concentric cables, subway cables and power cables
