    • The present invention is directed to a wire rope having a blackened finish designed for theatrical productions. The wire rope includes a plurality of strands that have a closed spiral arrangement with each other and are compacted. Each strand includes a center wire spirally surrounded by a plurality of inner wires that are spirally surrounded by a plurality of outer wires so that the outer wires completely encompass the inner wires. The center wire and the inner wires are made from a galvanized material and coated with a lubricant. The outer wires are made from a non-coated steel material. Each strand is compacted so the outer wires create a tight mechanical seal to protect the inner wires. The blackened finish on the wire rope is due to a black oxide coating treatment and provides for low visibility of the wire rope during theatrical performances.
    • 本发明涉及一种钢丝绳,其具有为戏剧制作而设计的黑化面。 钢丝绳包括彼此具有闭合螺旋布置并且被压实的多个股线。 每条线包括由多条内线螺旋地包围的中心线,所述内线由多根外线螺旋地包围,使得外线完全包围内线。 中心线和内线由镀锌材料制成并涂上润滑剂。 外线由未涂覆的钢材制成。 每根绞合线都被压实,所以外部的电线产生一个严密的机械密封来保护内部电线。 钢丝绳上的黑色涂层是由于黑色氧化物涂层处理,并且在戏剧表演期间提供钢丝绳的低能见度。
