Product Features

Advanced engineering and innovative design elements that deliver superior performance and reliability for fiber optic cable installations

Preformed Helical Armor Rod Structure

Industry-Leading Grip Technology utilizing high-strength aluminum-clad steel or galvanized steel preformed helical armor rods, providing 18-20% RTS (Rated Tensile Strength) uniform grip force.

The dual-layer inner and outer helical design offers load-bearing capacity from 10KN to 100KN, meeting various span requirements while effectively distributing stress concentration points.

High-Performance Composite Housing

Cast aluminum alloy housing with anodized surface treatment delivers superior corrosion resistance, achieving C5-M grade salt spray resistance (ISO 12944 standard).

Special chamfered interior design prevents stress concentration-induced cable damage, ensuring long-term reliability even in harsh environments.

Intelligent Rubber Insert System

EPDM high-elasticity rubber insert with embedded reinforcement frame features exceptional ozone resistance (no cracking at 1000ppm concentration) and temperature adaptation from -40°C to +100°C.

With compression set ≤15% (70°C × 22h) and >85% tensile strength retention after 2000-hour UV exposure, this system ensures consistent performance over time.

Anti-Vibration Design

Clamp ends feature gradual taper design to eliminate stress discontinuity points. Combined with the self-damping properties of elastic rubber, effectively suppresses aeolian vibration and sub-span oscillation.

This design significantly reduces cable fatigue damage risk, extending the operational life of your fiber optic infrastructure.

Full Stainless Steel Hardware

All bolts, washers manufactured from 304/316 stainless steel, equipped with anti-loosening spring washers and nylon lock nuts.

This hardware ensures sustained fastening force under vibration environments, maintaining clamp integrity even in challenging conditions.

Flexible Mounting Options

Multiple mounting configurations including U-Shaped Shackle (compatible with 5/8"-3/4" through-bolts), Right-Angle Loop (suitable for angle steel towers or concrete poles), and Multiple Bracket Compatibility.

Works with J-hooks, pole band brackets, and bolt-type brackets for versatile installation in various environments.

Model Selection Decision Tree

Step 1

Measure Cable Diameter

Use caliper to measure actual cable outer diameter

Select model with compatible diameter range

Step 2

Calculate Span Length

Measure distance between poles/towers

Short span (<100m) → Single clamp without armor rods

Medium span (100-400m) → Single clamp with armor rods

Long span (400-800m) → Reinforced single clamp or double clamp

Extra-long span (>800m) → Dual suspension system required

Step 3

Evaluate Line Angle

Straight line (0-10°) → Standard suspension clamp

Small angle (10-25°) → Suspension clamp acceptable

Medium angle (25-45°) → Use tension clamp instead

Large angle (>45°) → Use dead-end tension grip

Step 4

Consider Environmental Factors

Coastal areas → Specify 316 stainless steel hardware

High-voltage zones → Select all-dielectric models

Extreme temperature zones → Verify temperature rating

High-wind regions → Consider double clamp configuration
