摘　　要：OPPC作为一种新型的电力特种光缆,已经开始应用于一些10,35kV的输电线路工程中。作为电力特种光缆用金具应沿用预绞式的结构型式,以改善杆塔挂点处OPPC的受力状况,进而保护光单元。预绞式金具的标准主要有DL/T763-2001、DL/T766-2003和DL/T767-2003,但OPPC用金具及附件有其自身的特殊性,目前尚无相应的技术标准。As a new type of special optic fiber cable used in power system, OPPC has been installed on the transmission line of 10 kV and 35 kV. As the fitting specially used for power cable, it is better to use pre-twist structure to improve the force condition at the junctions of the tower so as to protect the optical units. The standards for pre-twist fittings are mainly DL/T 763-2001, DL/T 766-2003 and DUT 767-2003, but there are no corresponding technical standards for fittings and accessories used for OPPC because of their own particularities.
