Leaky cable systems are widely used where conventional antennas cannot provide reliable wireless coverage. Whether in underground mines, railway tunnels, highways, airports, industrial facilities, or military installations, a leaky feeder cable requires strong and durable mounting accessories for stable installation.
Among these accessories, SS (Stainless Steel) Clamps and PP (Polypropylene) Clamps play a vital role in securely holding the leaky cable throughout its route. Proper clamping ensures the cable remains aligned, protected from vibration, and performs consistently over years of operation.
At SRFS Teleinfra, high-quality Leaky Cable SS & PP Clamps are manufactured using premium materials to deliver long service life, corrosion resistance, and reliable mechanical support in demanding environments.
What Are Leaky Cable Clamps?
Leaky cable clamps are specialized cable holding accessories designed to support and secure radiating cables (leaky feeder cables) on walls, ceilings, tunnel surfaces, poles, and cable trays.
Their primary purpose is to:
- Hold the cable firmly without damaging the outer jacket
- Maintain proper cable alignment
- Prevent cable movement caused by vibration
- Simplify cable installation
- Increase cable lifespan
