The invention provides a lightweight easy-to-install composite insulation cross arm which comprises a core rod, an umbrella cover, a fixing fitting, a wire hanging fitting and a U-shaped hoop; the fixing fitting comprises a rectangular seamless steel pipe sleeving the core rod, a connecting seat arranged on the outer side of the rectangular seamless steel pipe, and a plurality of U-shaped clamping grooves formed in the connecting seat; a dismounting gap is formed between the inner side face of each U-shaped clamping groove and the rectangular seamless steel pipe; and the wire hanging fitting comprises a crimping groove used for crimping the end of the core rod, a wire hanging end arranged at the rear end of the crimping groove and used for wire binding, an arc-shaped groove formed in the wire hanging end and provided with an upward opening, and a paying-off pulley hanging ring arranged at the lower end of the wire hanging end and used for installing a pulley. The problems of difficulty in field installation and transportation, troublesome construction, heavy weight, difficulty in construction supply, poor installation stability and the like caused by an original fitting can be solved, and the lightweight easy-to-install composite insulation cross arm is simple in structure, convenient to bind and construct, high in safety, light in weight, small in occupied space, simple and convenient to install, safe to use and reliable in performance.
Description
technical field [0001] The invention relates to the technical field of insulating cross-arms, in particular to a lightweight and easy-to-install composite insulating cross-arm. Background technique [0002] At present, the composite insulating cross-arm is used in the insulated distribution line. The insulating cross-arm installed on the utility pole is mainly composed of an umbrella cover, a mandrel, a wire hanging fitting, a fixing fitting and a U-shaped hoop. The insulating cross-arm passes through the U-shaped After the hoop is connected with the fixed fittings, it is locked on the utility pole. However, the hanging wire fittings in the current insulating cross-arm are generally L-shaped, and the groove for supporting the wires is formed by the tail of the hanging wire fittings protruding upwards, and the raised The upper part is a solid structure, the overall weight is relatively large, and the outer side of the raised part is a large upper and lower small structure. Th...
