The installation technical characteristics of T-type and linear tension clamps are!
【概要描述】
What is a tension clamp? It is a connector for corner, connection and terminal. Spiral aluminum clad steel wire has strong tensile strength and no concentrated stress, which plays a role in protecting and assisting vibration reduction of optical cable. The complete set of optical cable tension fittings includes: Tension pre twisted wire and supporting connection fittings. The grip strength of the clamp shall not be less than 95% of the rated tensile strength of the optical cable, which is convenient and fast to install and reduces the construction cost. It is applicable to ADSS optical cable lines with span ≤ 100m and line angle < 25 °.
The application and clamping of t-wedge tension clamp is stable and stable. A cable slot for placing cables is set in the clamp body, a fastening piece is set above the cable slot, a U-shaped extrusion ring is set on the fastening piece, the two feet of the extrusion ring pass through the clamp body and are fastened by nuts, a guide block is set on the side of the fastening piece, and a guide block is set on the clamp body, It is matched with the guide groove on the clamp body, so even if one foot of the extrusion ring is fastened first, it will not cause the offset displacement of the fastening plate, so as to ensure that the fastening plate fixes the cable from top to bottom, and the clamping is stable and stable. The top of the fastening piece is provided with a groove as a positioning groove, and the U-shaped extrusion ring is clamped in the positioning groove. A positioning groove is arranged on the fastening piece, and the U-shaped extrusion ring is clamped in the positioning groove, which can not only prevent the deviation of the fastening piece, but also keep the clamping position fixed without sliding, so as to ensure the stable and stable clamping of the line.
In addition to the t-wedge type, there are also linear tension clamps for auxiliary parts of power equipment. The inner side of the clamp block is provided with a trunking for clamping cables. The trunking of the two clamp blocks correspond. The clamp block is arranged in the extrusion sleeve to form a sliding fit. The surface of the clamp block is provided with fastening teeth in one direction, and the inner surface of the extrusion sleeve is provided with anti reverse teeth in the opposite direction to the fastening teeth, The fastening teeth and the anti reverse teeth form an anti reverse mechanism. Using the sliding fit between the wire clamp block and the extrusion sleeve, when the two wire clamp blocks move in one direction, the wire slot is used to clamp the cable, and the fastening teeth and anti reverse teeth are used. When fastening, the wire clamp block will not move in the opposite direction to cause looseness, and even if there is vibration, the clamping state of the wire clamp will not be affected.
In the process of power grid construction, there is strict control over the use requirements of various power fittings. In addition, it is its practicability.
