Our products have long been used in the manufacture of cables, power and wires.

Insulating material for cables in electric cars

In electric cars, the electrical power to be transmitted is much higher than in an ordinary low-voltage electrical installation. Other requirements must be met for a high-voltage electrical installation: Due to the limited installation space, high requirements are placed on the insulation material, the electromagnetic shielding as well as the material thickness. TELESFOR is able to meet these requirements.

Tapes for round and profile wire production

Cut strips of polyester film (e.g. Mylar A, Hostaphan,) and Nomex in various widths are supplied. Deliveries are made on disc or cross spools.

Insulation systems for battery harnesses

TELESFOR manufactures insulation systems for the battery and cable industry from high-quality insulation materials, taking into account electromagnetic shielding and the need for optimum heat dissipation. In this context, emphasis is also placed on process-optimised further processing of the products.

Aluminium and polyester composite films for shielding

Electronic circuits or circuit components are subjected to electric fields. The resulting voltages have a destructive effect on such components and can lead to malfunctions.

To avoid this, the electrical cable is shielded by a closed metal sheath. Electrostatic shielding works on the principle of induction and is achieved in cables by means of a braided or continuous metal foil, which is usually insulated with PET film.

Shielding and mechanical protection are therefore provided in a single operation. There are different compositions of composite films with different material thicknesses. The composition depends on the shielding requirements.

Polypropylene films for the cable industry

TELESFOR supplies compact and foamed PP films for the insulation, separation and bonding of telecommunications, power and signal cables.

Insulation jointing papers

For paper-insulated earth cables, we supply punched parts made of special insulation paper. This enables cost-effective repair.

Relief elements made from extruded and CNC-milled GRP profiles

In our production, we manufacture and CNC-mill strain relief elements from extruded GRP (glass fibre plastic) profiles to relieve tensile forces.
