When performing a certain type of construction work, it is often necessary to use tools to fix objects. In such cases, special cable clamps are used. They are a metal-spring device equipped with 2 levers with a movable bracket. This design provides the most stable and durable fastening of any item on a cable of any thickness.
Where do they apply?
The cable clamps are most in demand in situations when it is necessary to connect several cables together or create a loop at the ends of the connecting element (cable, rope, and so on). Also, these mechanisms are used as connecting elements for wire braces and braces. Another clip can be used to connect the suspensions, where the cable itself is used directly as the supporting element.
Design
The cable clamps have a very simple design, which includes 2 hex nuts and a steel arc, which is usually made of high-quality and high-strength steel to ensure a reliable connection from both ends of the element. Additionally, this mechanism can be coated with a galvanic galvanizing layer, which provides the device with maximum resistance to external environmental influences, including corrosion.
When using this device, it is important to remember that only if all the installation rules are followed, you will be sure of the reliability of the fixed element. Otherwise, the element that is connected by a cable may break and fall down.
Varieties
At the moment, there are several varieties of these mechanisms, which differ in shape, design and material from which they are made. The most popular devices are wedge cable clamps. Where do they apply? Most often, a wedge clamp for a cable is used as a connecting element between copper and aluminum wires with a cross section from 35 to 100 mm 2 , including for steel cables. Also bolted clamps are used to connect steel-aluminum devices. The design of this mechanism involves the presence of a wear-resistant wedge and a housing made of forged cast iron steel. The wedge can also be made of cast iron or bronze or aluminum alloy. When installing aluminum and steel-aluminum wires of large cross-sections in bolt clamps along the axis of the wire, a special strip of soft aluminum tape is used to give the fastener a greater mechanical strength. Such clamps are tightened a second time after installation. This operation is performed as follows: first, the hinge part of the casing is pressed from aluminum, and then the steel anchor and the same aluminum casing with the steel mechanism inserted into it are pressed.
Cable clip: price
The cost of this device is from 140 to 500 rubles, depending on the type, design and spectrum of application of the device.
