Bolted Type Strain Clamp Tension Clamp NLL series
Product Description
Bolted Type Strain Clamp Tension Clamp - NLL series
A Bolted Type Tension Clamp is a type of electrical hardware used to secure overhead power lines to poles or towers. It consists of a metal band that is placed around the conductor, with bolts that are tightened to increase the tension and hold the conductor in place. This type of clamp is used for high tension applications and is designed to maintain its grip even under extreme weather conditions or high winds.
Bolted type tension clamp is also called dead end strain clamp or quadrant strain clamp. This product is NLL series, Aluminum Alloy Strain Clamp. One set of the clamp include U-bolt, washers, nuts and aluminum body.
Types of Bolted Type Tension Clamp
Depending on the conductor diameter, NLL tension clamp can be classified by the conductor diameter, there are NLL-1, NLL-2, NLL-3, NLL-4, NLL-5 (the same for the NLD series).
According to the material, the NLL series tension clamp is constructed from aluminum alloy, whereas the NLD series is comprised of malleable iron. This product is NLL series tension clamp.

Features of Bolted Type Tension Clamp
A Bolted Type Tension Clamp is a type of clamp used in electrical power transmission and distribution systems to secure power cables. Here are some of its key features:
Design: The clamp consists of two main components: a body and a bolt. The body is usually made of aluminum or other corrosion-resistant materials and is designed to provide a secure grip on the cable. The bolt is typically made of stainless steel and is used to tighten the clamp onto the cable.
Easy Installation: The bolted type tension clamp is designed for easy installation, as it can be tightened by hand or with a wrench. This makes it suitable for use in remote locations or in situations where it is not feasible to use specialized tools.
Cable Size Compatibility: Bolted type tension clamps are available in a range of sizes to accommodate different cable diameters. This allows them to be used in a variety of applications, from low-voltage power distribution to high-voltage transmission systems.
High Strength: The clamps are designed to withstand high levels of tension, making them suitable for use in high-stress applications. They are also engineered to resist loosening over time, ensuring a secure connection for the life of the system.
Corrosion Resistance: The materials used in the construction of bolted type tension clamps are highly resistant to corrosion, making them suitable for use in harsh environments.
Versatility: Bolted type tension clamps are versatile and can be used in a variety of applications, including power transmission and distribution, grounding systems, and cable support systems.
Cost-Effective: Compared to other types of clamps, bolted type tension clamps are relatively inexpensive and provide an economical solution for securing power cables.
