Abstract

The invention provides a protective sheath (10) for at least one electrical conductor (24). The protective sheath (10) comprises a multilayer structure including at least three layers (12, 14, 16), wherein an inner layer (16) is formed by a mixture of aramid fibers and glass fibers and a middle layer (14) is formed by aramid fibers or a mixture of aramid fibers and glass fibers is formed, and theprotective sheath (10) is characterized in that an outer layer (12) is formed by a thermoplastic elastomer. The invention further provides a wire assembly comprising the protective sheath (10) provided by the invention and at least one electrical conductor (24), in particular at least one electrical conductor (24) of a 48V DC power source in a motor vehicle, and the invention relates to an application of the protective sheath (10) provided by the invention for at least one electrical conductor (24) of a 48V DC power source in a motor vehicle.

Description

technical field [0001] The invention relates to a protective sheath for at least one electrical conductor comprising a multilayer construction of at least three layers, wherein the inner layer is formed from a mixture of aramid and glass fibers and the middle layer is formed from aramid or from aramid and A mixture of glass fibers is formed. Background technique [0002] Modern automobiles have a high demand for electrical energy (power) per unit of time due to the extensive use of electric motors. In physics, electrical power is the product of voltage and current intensity. For common 12-volt automotive circuits, the high power demand per unit of time means high currents, which in turn result in large conductor cross-sections. A large wire cross section increases the weight of the wire and the manufacturing costs. If you want to increase the power at the same current level, you can also increase the voltage. Therefore, in the automotive field, there is a tendency to ado...
