Characteristic
Anchor clamp for self-supporting insulated wires is a device designed to securely fix the SAP between the supports on which they are attached.
In the manufacture of clamping devices for self-supporting insulated wiring, aluminum-based alloys are used, galvanized steel or very durable thermoplastic. Let's consider the main characteristics of these products.
- Simplicity and speed of installation. The work does not require special training of specialists, and this significantly reduces the time spent on laying power lines.
- Security. The design of the mounts is very well thought out, which helps to reduce injuries to employees and damage to cables during installation.
- The opportunity to save money. Thanks to the simple and reliable design, the consumption of materials for the installation of electrical networks is reduced.
- Reliability. Anchors serve well when exposed to any atmospheric conditions.
And also one of the features of the clamps is that they cannot be repaired: if they fail, they must be replaced.
Dimensions (edit)
The use and parameters of anchor clamps, as well as their types, are established by GOST 17613-80. For more information on the regulations, please review the relevant standards.
Let's consider the most common options.
Anchor clamps 4x16 mm, 2x16 mm, 4x50 mm, 4x25 mm, 4x35 mm, 4x70 mm, 4x95 mm, 4x120 mm, 4x185 mm, 4x150 mm, 4x120 mm, 4x185 mm are used most effectively for laying air electric and subscriber lines. In this case, the first number indicates the number of cores that the anchor can carry, and the second indicates the diameter of these wires.
The range of cross-sectional diameters of wires that can be fixed in anchor-type fasteners is huge. These can be thin cables with a diameter from 3 to 8 mm, medium cables from 25 to 50 mm, as well as large bundles from 150 to 185 mm. The anchor clamp PA-4120 4x50-120 mm2 and RA 1500 has proven itself very well when laying air lines.
