NLD / ND Bolted Strain Clamps

As a premier manufacturer and reliable supplier of utility hardware, we provide premium NLD And ND Type Tension Clamps (bolt Type) engineered for secure and efficient overhead line construction. Designed to meet the rigorous demands of modern electrical infrastructure, these clamps ensure unyielding tensioning without compromising the integrity of your conductors.

• Engineered specifically for 10KV and below power distribution lines.

• Robust construction featuring exceptional electrochemical corrosion resistance.

• Streamlined design enabling rapid, single-person installation.

• Ideal for terminal, branch, tension, and corner poles.

Beyond their physical robustness, these tension clamps are engineered to solve the chronic challenge of structural fatigue in power distribution networks. They seamlessly integrate into your existing infrastructure, providing a fail-safe anchor at crucial junction points along the grid. The intelligent contouring of the clamp body distributes mechanical stress evenly across the conductor, preventing the localized fraying and metal fatigue that often plague lesser fittings. This translates directly to fewer service interruptions, significantly lower operational overhead, and a fortified electrical grid that maintains its integrity over decades of continuous exposure to the elements.

Unmatched Structural Integrity and Conductor Protection

Our tension clamps are meticulously engineered to elevate the safety and efficiency of your power distribution networks. By focusing on precision mechanics and material excellence, these components deliver outstanding operational advantages that protect your infrastructure investments.

• The stress distribution of the wire clamp on the stranded wire is uniform, without damaging the stranded wire, which improves the anti vibration ability of the stranded wire and greatly extends the service life of the wire.

• Good corrosion resistance, using high-quality materials that are completely consistent with the wire, ensuring that the wire clamp has strong resistance to electrochemical corrosion.

• Suitable for the construction of 10KV and below power lines, used at terminal poles, branch poles, tension poles, and corner poles of power lines.

Streamlined Deployment and System Upkeep

Time and labor are critical assets in large-scale infrastructure projects. These clamps are purposefully designed to eliminate complex assembly processes, directly impacting your project timelines and improving overall maintenance workflows.

• Easy to install, convenient for construction, can greatly shorten construction time, does not require any special tools, and can be completed by one person.

• The installation quality of the wire clamp is easy to ensure, and can be inspected with the naked eye without the need for specialized training.

• The maintenance and replacement of bolt type tension clamps are relatively simple. Due to its reasonable structural design, it can be easily disassembled and replaced. This reduces maintenance costs and time, and improves the maintenance efficiency of the power system.

Material & Corrosion Resistance

Procurement specialists highly prioritize the lifespan of power fittings in harsh, unforgiving outdoor environments. Our clamps utilize premium materials, including high-strength steel, malleable cast iron, and hot-dip galvanized finishes that perfectly match the conductors. This superior construction provides extreme resistance to electrochemical corrosion, drastically reducing the frequency of long-term replacements and safeguarding your infrastructure investments against premature degradation.

Wire Protection & Anti-vibration

Stress concentration damage from inferior clamps directly compromises overhead line safety. The scientific structural design of our clamps ensures that the gripping force on the stranded wire remains perfectly uniform. This non-destructive hold significantly enhances the anti-vibration capabilities of the conductors, mitigating the effects of aeolian vibration and ultimately prolonging the overall service life of your suspended lines.

Installation Efficiency

Labor costs and construction cycles are vital considerations for engineering contractors aiming to optimize project margins. The intuitive bolt-type design allows a single operator to complete both installation and dismantling effortlessly. Eliminating the need for specialized hydraulic tools or extensive technician training, the visual inspection capability slashes construction time and accelerates project delivery without sacrificing safety.

Application & Compatibility

Clarity in application scope is necessary for accurate bulk procurement planning. Specifically engineered for 10KV and below power lines, these clamps are universally applicable at terminal poles, branch poles, tension poles, and corner poles. They offer flawless compatibility with various specifications of small and medium cross-section aluminum stranded wires and steel-core aluminum stranded wires, making them a versatile addition to your hardware inventory.

Maintenance & Replacement

Long-term operational costs represent a core pain point in managing extensive power systems. As a removable type tension clamp, its highly rational structural design makes subsequent field inspections and replacements incredibly straightforward. This operational efficiency effectively lowers the comprehensive maintenance costs of the power system and significantly boosts the speed of emergency grid repairs during critical outages.
