A flexible electric line for movable loads is specified which has at least two wires, in each case consisting of an electrical conductor and an insulation surrounding it, as stranded elements which are stranded around a core consisting of insulating material with dents extending in the longitudinal direction in which the stranded elements lie. In the core, a non-metallic tension- and compression-resistant carrier enclosed by a layer of insulating material is centrally arranged. The layer of insulating material consists of an impressible material remaining permanently elastic, which completely fills the internal interstices between the stranded elements, and it is surrounded by a sliding layer of a material having good sliding characteristics compared with the stranded elements.

Flexible electric line

An insulated electrical conductor with preserved functionality in case of fire includes a metallic conductor, a first glass and/or mica containing layer, which is applied to the conductor, and a second plastic layer sheathing the first layer. The first layer consists of at least two longitudinally introduced strips of glass and/or mica applied to the conductor, the width of which is selected such that each of the strips overlaps itself by at least 50%.

Insulated electrical conductor with preserved functionality in case of fire

An electric installation cable in which the insulated wires forming the core and serving to conduct electricity are bound together as one unit. For the simultaneous, undisturbed utilization of the cable for high frequency signals, the unit is made up of 4 cores (A) bound together to form a star-quad. A shield ( ) made up of a plastic film ( ) coated on both sides with aluminum is arranged over the cores (A). Tinned copper wires ( ) are wrapped around the shield ( ) to function as a ground wire ( ) and a coat ( ) of insulation material is arranged around the tinned copper wires ( ).

Electric installation cable

A flexible electrical cable is formed of a cable core made of a plurality of insulated conductors ( ) that are stranded together, an inner sheath ( ) that fills up the interstices between strands, a wrapping ( ) resting on the inner sheath ( ), armor braiding ( ) with a 30%-80% optical coverage, and a plastic outer sheath ( ) penetrating the interstices between the braiding ( ).
