Product Description

Enquiring about strain clamps? We've got you covered with our range of options. Choose from aluminium alloy or forged iron, depending on your specific needs. Our strain clamps have a breaking load of 20KN to 120KN, so you can trust that they will stay securely in place. To ensure we provide you with the best product for your requirements, please advise us with the model number or provide a drawing when making your enquiry. Our options include bolt type strain clamps and suspension clamps, and we're always happy to recommend the best choice for your project.

Compression type and bolt type are the two main types of strain clamps that are commonly used in various applications. These clamps play a crucial role in fixing conductors and ground wires to insulators or link fittings on tower arms or substation structures. Their construction and mounting methods determine their functionality.
Strain clamps are specifically designed to provide a secure and reliable connection between conductors, ground wires, and the supporting structures. By using these clamps, the risk of conductor and ground wire disconnection or damage is significantly reduced.
The compression type strain clamp is constructed in a way that it applies pressure or force to hold the conductor or ground wire firmly in place. This type of clamp requires proper compression tools to ensure a tight and secure grip. It is a popular choice due to its effectiveness and ease of installation.
On the other hand, the bolt type strain clamp features a construction that uses bolts to hold the conductor or ground wire in position. These clamps are typically adjustable, allowing for precise tightening. They require the use of appropriate tools for torque control to ensure proper installation.
Both compression type and bolt type strain clamps serve the same purpose of securing conductors and ground wires. The choice between the two depends on various factors, including the specific application requirements and the preferences of the installer.

The NLL series aluminium alloy strain clamp, in a bolt type configuration, is specifically designed for use with AAC and ACSR conductors. These conductors can either be wound or have armour rods installed for additional protection. The primary function of the strain clamp is to secure and support the conductors in various applications.
