Wedge type tension clamp H4

Anchoring, wedge-shaped tension clamp H3, H4 and H6 models are suitable for self-supporting aerial or ADSS fiber optic cables, electric cables and for “figure 8”-like cables with external load-bearing element. This clamp provides you an ability to fasten the cable, without exposing the cable or separating supporting element. The installation does not cause any damage to the sheath. This clamp has several names: wedge type tension clamp for cable suspension, dead-end clamp, wedge fastening clamp, anchor clamp and similar.

There are few steps of fastening the cable using this anchor clamp:
• partial extension of the wedges into the housing;
• cable insertion;
• cable clamping;
• insertion of a steel loop.

With the use of this clamp, it is possible to fasten two types of cables: circular cross-section cable and type 8 cables.

Clamp H3, H4 and H6 models consists of a plastic frost and UV resistant body, polymeric wedges and loop made of a hot-dip galvanized steel.

Allows an easy manual installation without any tools for building overhead communication lines on utility poles. It fastens by a loop to the utility poles with the help of hooks, brackets, etc.

The loop is made of high quality galvanized steel wire.

Wedge type tension clamps is used for fast fastening of electric and fiber optic cables, ADSS cables, with the following parameters according to the model:

• H3, H3d – for round cables with diameter from 0,15 to 0,275” (4-7mm);

• H4, H4d – for oval or flat cables with diameter from 0,15 to 0,31” (4-8 mm);

• H6, H6d – for round cables with diameter from 0,23 to 0,35” (6-9 mm);

• H3, H3d, H6 and H6d – for self-supporting aerial cables, ADSS or “figure 8” suspension cables with external load-bearing element with diameter from 0,15 to 0,35” (4-9 mm).

Technical characteristics for H3, H4 and H6 models:
Maximum spans between fastening points – 262 ft. (80 m)
Working load – up to 1,4 kN
Breaking load – 1,8 kN
Loop thickness — 0,195” (5 mm)
Operating temperatures -40 to +140°F (-40°C – +60°C)

Distinctive feature of our clamps is that under extreme conditions (frosting, trees falling, hurricanes, etc.) the clamp is destroyed without the damage to the cable which, in some cases, prevents line breakage.

Our tension clamps are made of high-quality materials and are able to operate under the extreme conditions and loads.

It designed for a fast mounting of self-supporting optical, electrical and other cables on the utility poles.

Cable is not damaged when using this tension anchor clamp. And wedges for an even distribution of a load on the cable sheath and for reducing mechanical stress in order to protect cables from tearing during the increased load - icing, falling branches an cables, hurricane, strong wind, etc.
