Cable clamps: purpose and device

When performing a certain type of construction work, it is often necessary to use tools to fix objects. In such cases, special clips for the cable are used. They are metal-spring-loaded devices equipped with 2 levers with a movable bracket. This design ensures the maximum durable and strong fixing of any object on the cable of any thickness.

Where do they apply?

The most demanded clips for the cable in situations where it is necessary to connect several cables together or create a loop at the ends of the connecting element (cable, rope , etc.). Also, these mechanisms are used as connecting elements for wire stretch marks and braces. Another clamp can be used to connect the suspension, where the cable itself is used directly by the cable itself.

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. In addition, this mechanism can be covered with a layer of galvanized galvanizing, which provides the device with maximum resistance to external influences of the environment, including corrosion.

When using this device, it is important to remember that only if all the installation rules are observed, you will be sure of the reliability of the fixed element. Otherwise, the element that is connected by a cable can break off and fall down.

Varieties

At the moment there are several varieties of these mechanisms, which differ in the form, design and material from which they are made. The most popular devices are wedge clamps for cable. Where do they apply? Most often, a wedge clip 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. Bolt clamps are also used to connect steel-aluminum devices. The construction of this mechanism assumes the presence of a wear-resistant wedge and a body made of forged iron steel. The wedge can also be made of cast iron, bronze or aluminum alloy. When installing aluminum and steel-aluminum conductors of large cross sections, a special spacer made of soft aluminum tape is used in the bolt clamps along the wire axis to give the attachment more mechanical strength. Such clamps are retightened 10 days after installation. This operation is performed as follows: first, the loop part of the body is pressed from aluminum, and then - the steel anchor and the same aluminum body with the steel mechanism inserted into it.

Cable clamp: price

The cost of this device is from 140 to 500 rubles, depending on the type, design and scope of the device.
