Introduction to the production process of new energy wires and cables--application of talcum powder

China [CN]

The friction between the cable core wires extends the service life of the cable core wires. The reason why talcum powder can play such a role is that the talcum powder particles can slide under the cable sheath, and the particles can rub longitudinally.

During the production process, the insulating layer plastic and the cable sheath material must be properly isolated. First, the core wires are twisted together, and then the liquid plastic of the cable sheath is poured around them. If there is no talcum powder, the heat of the cable sheath will soften the surface of the insulation layer, which will cause the insulation layer to adhere to the cable sheath.

Talc powder not only absorbs moisture, but also can be used as an isolating agent and lubricant. For example, in the cable industry, talcum powder can separate the cable sheath from the cable core wire.

Application: In addition, talcum powder can be used in sports to reduce friction; however, when used on cables, it can also reduce the friction between the cable sheath and the cable core wire. In this way, the service life of the cable will be reduced, and it is also a poor processing solution. The presence of talcum powder also makes cable stripping smoother, because the outer sheath of the cable can be quickly stripped after circumcision.

Of course, the production of cables of different specifications and models requires different R&D technologies. If you need to know the specific product situation, please visit: https://www.omgevcable.com
