The Dead End Clamps are typically the first piece of network hardware to be installed during an overhead fiber optic installation or the expansion of a copper cabling. Two cable fastening solutions—dead-ending or anchoring & suspension—are to be utilized to accomplish its roll-out on telecom & power lines in strict regard to engineering requirements and ensure a lasting implementation.
When deciding between Dead End Clamp as well as a suspension device, it is important to think about the layout of the cable being installed and, more importantly, your network. You will get a comprehensive guide to the many technological options for overhead cable attaching, outlining all the crucial details you'll need to know before making your final decision.
Clamps and dead-ends for constructing FTTH networks -
Depending on the area of the network being installed, wire or fiber optic cables may be anchored using a helical dead end, anchor clamp, or drop clamp. Cables can be terminated without strain on the telecommunications pole or cross-arm because of anchor clamps. They must be installed not just at the beginning and end of the telecommunications network and also when:
· When the line has an angle greater than 25 degrees at one side along another road junction due to difficult terrain or unequal neighboring spans, a cable down-lead toward the distribution box is required at every 5 poles in alignment arrangements.
· Overhead telecommunications wire terminations: potential remedies and practical uses.
There are now four technology options available for use in dead-end applications involving aerial cables:
· Conical-wedge anchor clamps
This technique is based on a straightforward principle: increasing cable tension by tightening the clamp. Conical-wedge anchor clamps may be installed quickly and easily without special equipment, allowing for fine-tuning the cable sag by hand. These are the ideal solution for the round cables using FRP rods or figure-8 cables using steel or dielectric messenger. To a large extent, this technology answer has found the most adoption in distribution systems.
· Clamps for holding mandrels at a downward angle -
This product prevents cables from being damage by piston effects by having the cable wind itself tightly around the mandrel. Dead End Clamp allows for a manual adjustment of the cable sag and requires no special tools for installation. Because it complied with small-bore cables lacking FRP rods and/or exhibiting a non-dense inner sheath construction, this dropped cable fallen clamp is strongly recommended for last mile access network.
· Dead End Clamp drop like a wedge
These drop clamps have a wedge shape tailored to the specific geometry of the clamped cable. Whether you're using fiber optic or copper cabling, this solution can be used on last-mile access networks having spans of up to 70 meters. Clamps with enclosing wedges are an advanced technology that has been created to fulfill the rigid optical round cable requirements. When used in FTTH deployments, these anchor clamps protect the cable's integrity and functionality from strain.
· Turning points remain the same
Helical dead-ends, a product of prepared technology, allow for the aerial installation of circular cables in distribution systems with limited space between nodes. With such a broad contact area with the cables, spirals have shown to be effective even under challenging installation circumstances. These Dead End Clamps are discrete, but they need more parts and time to set up than alternatives leading nowhere.
