Short-span tapered strain clamp for ADSS optical cable

Abstract

The invention relates to a short-span tapered strain clamp for an ADSS optical cable, and belongs to the technical field of ADSS optical cable installation. A wire clamp body is in tapered cooperation with a combined wedge, the length of a hardware body is one fourth that of a pre-twisted hardware under the same grip, hidden safety troubles caused by that the hardware touches wires in the construction process are eliminated, and the strain clamp can be adapted to ADSS optical cables of different external diameters. The short-span tapered strain clamp for the ADSS optical cable comprises the wire clamp body, the combined wedge and a suspension ring, wherein the wire clamp body comprises an external casing and an internal interlayer, the external casing includes a truncated conical casing structure without bottom, the wire clamp body can be divided into two halves along the plane of the central axis, the combined wedge is arranged in the wire clamp body and composed of multiple wedge bodies, and the suspension ring is arranged in the rear portion of the wire clamp body. The short-span tapered strain clamp can be widely applied to the technical field of ADSS optical cable installation.

Description

technical field [0001] The invention discloses an ADSS optical cable short-span tapered tension clamp, belonging to the technical field of ADSS optical cable installation. Background technique [0002] At present, almost all ADSS optical cable fittings use pre-twisted fittings, because of their advantages of easy installation and uniform grip, they play an irreplaceable role for other types of fittings; but pre-twisted fittings also have disadvantages. Twisted wire fittings are likely to cause safety accidents during the construction process. This is due to the characteristics of low-voltage lines of 10KV and below. In the complex environment of the city, during actual construction, in order to avoid being hung up by large vehicles and machinery, the optical cable will be further hung up. The actual hanging point is sometimes close to the cross arm, and the distance from the power line is less than 1m. This is a distance where dangerous accidents are likely to occur. During...

[0002] At present, almost all ADSS optical cable fittings use pre-twisted fittings, because of their advantages of easy installation and uniform grip, they play an irreplaceable role for other types of fittings; but pre-twisted fittings also have disadvantages. Twisted wire fittings are likely to cause safety accidents during the construction process. This is due to the characteristics of low-voltage lines of 10KV and below. In the complex environment of the city, during actual construction, in order to avoid being hung up by large vehicles and machinery, the optical cable will be further hung up. The actual hanging point is sometimes close to the cross arm, and the distance from the power line is less than 1m. This is a distance where dangerous accidents are likely to occur. During the construction process, it is often necessary to operate the pre-twisted wire in the air. The shortest pre-twisted wire length is generally about 1.5m. If you don’t pay attention during the process, you will touch the wires and cause electric shock accidents. In fact, such accidents happen from time to time. Twisted fittings have poor adaptability, one kind of outer diameter optical cable can only be equipped with one kind of pre-twisted wire, otherwise the grip strength will not meet the requirements, and the use is very limited, which is quite inconvenient
