Abstract

The invention discloses an optical fiber lead-down device for a composite phase line optical cable of a fully insulated optical unit, comprising a wire clamp unit, which includes a first clamp plate and a second clamp plate hinged with the first clamp plate, the first clamp plate includes a first clamp plate. a groove and a first hinge end and a first lower end located on both sides of the first groove, the second clamping plate includes a second groove and a second hinge end and a second lower end located on both sides of the second groove , the first hinged end and the second hinged end are hinged; the structures of the first lower end and the second lower end are completely symmetrical, and a guide groove is arranged between the first groove and the edge of the first splint; The section of the insulated optical unit composite phase line optical cable that needs to be led down is placed in the clamp unit, and then the stripped optical unit (optical fiber) is led out along the guide groove, and the position of the guide tube in the fan-shaped groove is adjusted according to the required leading angle. Bending and breaking will not occur.

Description

technical field [0001] The invention relates to the field of IOPPC communication, in particular to an optical fiber lead-down device of a composite phase line optical cable of a fully insulated optical unit. Background technique [0002] Insulated Optical-unit Phase Conductor (IOPPC) is a subset of optical fiber composite phase conductor OPPC. By replacing the original stainless steel tube covering the fiber bundle with an insulating material, optoelectronic separation becomes simple and easy. It can be connected on the ground and lead down at any position, which expands the application scope of the optical fiber composite phase line. It is an optical cable that combines optical fiber units in the phase line. It has dual functions of phase line and communication. It is mainly used for voltage levels below 110kV, suburban areas. Distribution network, rural power grid. However, when the composite phase line of the fully insulated optical unit is photoelectrically separated, t...
