摘要

The cable consists of: (a) a thermoplastic material housing Housing Housing Housing Housing Housing integrated with a semi rectangular geometric layout; and (b) one or more drive circuits arranged uniformly in the cable internal structure, 1. As self-sustaining member, it is composed of two metal conductive elements or glass fiber impregnated with polymer or Kevlar tape. Each member is parallel to and opposite to the main transmission line on its section;The second circuit is a core core consisting of two braided drivers, each of which is wound to the core with a layer of thermoplastic compound and an expanded powder. Comment more than a month agoThe balance circuit shows 100 nanosecond blocking, allowing digital signals to be transmitted at 155 nanoseconds. The expandable powder is a kind of polyaryl (sodium acrylate) polyamide, which is made into a layer of coating by a voltage device and applied on the pair of the outer polyaryl (a) braiding.
