Product Description
The XGU series tension clamps manufactured by Yueqing JASCO Electric comply with IEC 61284 and GB/T 2314 standards. These products are widely used in urban and rural power grid expansions, overhead lines for photovoltaic projects, and domestic power plant construction.
This series of clamps is designed to withstand tension from both static loads and dynamic operational loads (including wind forces) and is compatible with various conductor types, such as ACSR (Aluminum Conductor Steel Reinforced), AAC (All Aluminum Conductor), and AAAC (All Aluminum Alloy Conductor).


All components undergo hot-dip galvanizing; the main body is made of high-strength cast steel, while the accompanying parts are made of carbon steel, ensuring superior mechanical strength and corrosion resistance for long-term outdoor use. The curved groove fits the conductor's outer diameter perfectly and distributes stress evenly, preventing damage or corrosion at the connection point. The clamp's design offers a degree of flexibility, allowing it to absorb wind-induced vibrations, effectively reduce resistance, and extend the service life of overhead lines.
The assembly consists of U-bolts, a cast clamp body, and a protective liner (pressure plate). Installation is quick and simple, requiring only a standard wrench; locking pins and nuts further enhance clamping force, ensuring stability and reliability even under harsh weather conditions.
As a professional manufacturer, JASCO also provides OEM services and customized surface coating solutions to global customers.
Product Specification

Product Advantages
Superior Corrosion Resistance
The clamp body and handle are manufactured from high-quality aluminum, offering excellent rust and corrosion resistance. This ensures product durability in outdoor environments, ranging from tropical climates to coastal regions.
Optimized Conductor Protection Design
The curved groove design ensures a snug fit with the conductor and uniform pressure distribution. This prevents nicks or abrasions on ACSR (Aluminum Conductor Steel Reinforced) or AAC (All Aluminum Conductor) lines, effectively protecting the conductor during installation.
Vibration Dampening and Loss Reduction
The clamp helps mitigate the impact of wind-induced vibration on overhead lines, reducing the risk of conductor damage and extending the service life of the line.
High Mechanical Strength and Anti-Loosening / Anti-Corrosion System
Constructed from low-carbon and high-quality carbon steel, the clamp features anti-loosening nuts and locking pins to prevent loosening caused by wind or dust accumulation. Its robust clamping force fully meets line load requirements.
Quick and Easy Installation
The installation process is simple and efficient. Field installation requires only a standard wrench - no specialized tools are needed - thereby reducing labor time.
Customized Specifications and Services
The XGU series covers a wide range of conductor specifications. JASCO offers OEM customization and specialized components compliant with IEC 61284 and GB/T 2314 standards to meet the requirements of international power engineering projects.
