Product Introduction

Tension clamp (also known as strain clamp or dead end clamp) is a specialized metal fixture designed to secure electrical wires or cables, withstanding significant axial tension. Its critical roles are ensuring wire stability at dead-end, angle, or terminal points and transferring mechanical loads effectively to towers or support structures. For detailed product information and technical documentation, visit our Tension Clamp, Strain Clamp, Dead-End Clamp page.

  • Material: High-strength aluminum alloys, SG ductile iron, galvanized bolts/nuts for corrosion resistance
  • Structure: Body, pressure plate/keeper, U-bolts, and hardware

4. Applications of wire cable stop clamp in Modern Infrastructure

The versatility of wire cable stop clamp makes it integral in a multitude of environments:

  • Overhead Power Lines: Ensuring reliable conductor dead-end and tensioning on transmission and distribution networks.
  • Substation Busbar Anchoring: Used in tensioning busbar connections for sustainability and fault-resilience.
  • Telecom Lines: Securing communication wires and fiber optic cables in long-span and terminal scenarios.
  • Railway Electrification: For catenary tension, anchoring messenger and contact wires safely.
  • Underground/Distribution Systems: As a critical fitting to manage load transfer where cabling transitions from underground to overhead.
  • Industrial Automation: To anchor control/automation wiring, especially in high-vibration or corrosive environments with cable relief clamp variants.

The above scenarios demand outstanding mechanical performance, temperature endurance, corrosion resistance, and simplified on-site assembly—all of which Handan Samao Electric Power Equipment Manufacturing Co., LTD. designs for in every wire cable stop clamp.

5. Technical FAQ Section

Q1: What materials are used for wire cable stop clamp?
A: Premium aluminum alloy (6061-T6 or 7075), SG ductile iron for the body, and hot-dip galvanized steel for hardware. These materials are chosen for a balance of strength, ductility, and corrosion resistance. [ResearchGate Article]
Q2: What are the standard specifications (sizes/loads) for tension, strain, and dead-end clamps?
A: Main conductor diameters: 7–36mm (custom up to 40mm). Typical ultimate tensile load rating: 20–120kN. These specs are customized to application voltage and span length.
Q3: Which industry standards must your strain clamp for overhead line meet?
A: All clamps are manufactured and tested to IEC 61284, GB/T 2314, IEEE C135.41, and often also meet local grid regulations for performance and safety.
Q4: How is corrosion protection achieved?
A: Materials utilize anti-oxide alloy compositions plus zinc-rich hot-dip galvanizing. Optionally, powder coating or fluoropolymer layers enhance harsh environment endurance, achieving >500h salt spray resistance.
Q5: What are the installation standards?
A: Installation follows IEEE 524 and IEC 61284 protocols, ensuring correct torque, alignment, and insulation clearance. Detailed guides and torque charts are included in our technical catalog.
Q6: Can your products be used for both aluminum and steel-core conductors?
A: Yes, our tension lock clamp and related products are compatible with ACSR, AAC, AAAC, and copper conductors. Specific liners or keeper shapes prevent conductor damage, maximizing longevity.
Q7: What is a cable relief clamp and when is it needed?
A: Cable relief clamp is optimized for regions with microvibration, thermal expansion, or minor cable shift. It gently anchors cables while reducing strain on insulation or sheath, vital for control wires and automation systems.
