Heavy Duty Corner Ground Roller With Triple Sheave Design For Power Construction
Product Introduction
Specialized cable guiding equipment for 90-degree corner installations
Triple-sheave design minimizes cable bending radius
Essential for protecting high-voltage cables during directional changes
Key Features
Advanced Sheave System
Three precision-aligned sheaves create optimal cable path
Each sheave rotates independently to reduce friction
Robust Construction
Forged aluminum frame withstands extreme pulling forces
Reinforced mounting points for secure anchoring
Cable Protection
Nylon-coated sheave surfaces prevent jacket abrasion
Smooth radius exceeds IEEE minimum bend requirements
Operational Efficiency
Quick-release pins enable rapid sheave changes
Ground spikes included for temporary installations
Safety Enhancements
Non-conductive materials for live work applications
High-visibility safety yellow powder coating
Typical Applications
Street corner underground cable installations
Substation entrance/exit cable routing
Industrial plant cable tray transitions
Bridge crossing cable directional changes
Installation Advantages
Fits standard cable pulling equipment setups
Compatible with both horizontal and vertical mounting
Requires no special tools for assembly
Maintenance Benefits
Sealed bearings prevent dirt contamination
All moving parts are self-lubricating
Modular design simplifies component replacement
