Abstract:
The present invention is directed to a high voltage, insulated electrical power cable suitable for use adjacent to one or more low power signal communications conductors in metal or plastic conduit or raceway. In one preferred embodiment, the power cable includes a first group of one or more conductors for supplying power and a power conductor insulation jacket enclosing the first group of one or more conductors. The power conductor insulation jacket includes a soft magnetic material that that functions as an electromagnetic field shield in the radio frequency range of approximately 1 megahertz to 400 megahertz thereby protecting the integrity of signals transmitted on the adjacent signal communications conductors.

본 발명은, 연속적으로 이송되는 적어도 하나의 세미-플렉서블 케이블을 사이에 두고, 제1금속 시트와 제2금속 시트를 연속적으로 덮는 단계와, 상기 적어도 하나의 세미-플렉서블 케이블을 상기 제1금속 시트와 상기 제2금속 시트 사이에 고정시키도록, 가열 금형 내에서 상기 제1금속 시트와 상기 제2금속 시트를 서로 열융착 시켜서 세미-플렉서블 케이블 결합체를 생성하는 단계와, 상기 생성된 세미-플렉서블 케이블 결합체를 냉각시키는 단계를 포함하는 세미-플렉서블 케이블 결합체의 제조 방법을 제공한다. 따라서, 세미 플렉서블 케이블이 제1,2금속 시트들에 의하여 보호되기 때문에, 상기 세미-플렉서블 케이블의 손상 가능성이 크게 감소한다. 또한, 상기 세미-플렉서블 케이블이 상기 제1,2금속 시트들에 의하여 덮이기 때문에, 삽입 손실이 현저하게 감소된다.
Abstract:
The present invention provides a method of manufacturing a semi-flexible cable assembly, comprising a step wherein one or more semi-flexible cables are continuously transferred between and continuously covered by a first metal sheet and a second metal sheet; a step wherein a semi-flexible cable assembly is produced by heat-welding said first metal sheet and said second metal sheet in a heated mould, so as to fix said one or more semi-flexible cables in place between said first metal sheet and said second metal sheet; and a step wherein the resulting semi-flexible cable assembly is cooled. Therefore, the likelihood of damage to said semi-flexible cable is greatly reduced because the semi-flexible cable is protected by the first and second metal sheets. In addition, insertion loss is markedly reduced because said semi-flexible cable is covered by said first and second metal sheets.

The present invention is directed to a high voltage, insulated electrical power cable (12) suitable for use adjacent to one or more low power signal communications conductors (30) in metal or plastic conduit or raceway (60). In one preferred embodiment, the power cable includes a first group of one or more conductors for supplying power and a power conductor insulation jacket (21b) enclosing the first group of one or more conductors. The power conductor insulation jacket includes a soft magnetic material that that functions as an electromagnetic field shield in the radio frequency range of approximately 1 megahertz to 400 megahertz thereby protecting the integrity of signals transmitted on the adjacent signal communications conductors.

Abstract:
An electric power distributing bus-bar or cable comprising a carrying line (10) and electric conductor parts (11-15). The carrying line (10) and the conductor parts (11-15) are disposed in a common electrically insulated jacket (16) and the electric conduction capacity of the carrying line (10) is adapted to and preferably similar to that of each one of the conductor parts so that the carrying line (10) may be used as a complementary conductor.
