Cable-blowing machine is a device used to install communication optical cables and electrical cables (such as fiber optic cables, coaxial cables, and multi-core cables) into pre-installed ducts. It operates using an air blowing method, where the cable is pushed into the conduit by a mechanical cable pusher. The powerful airflow generated by an air compressor creates a drag force on the cable's surface, propelling it forward. This installation method differs from traditional pulling methods as the cable's top end experiences less force, reducing cable stress and extending its lifespan. Additionally, the cable-blowing process is relatively simple and easy to learn. It is suitable for armored fiber optic cables and is less affected by bends in the conduit.
Here are some key technical parameters and accessory options for a cable-blowing machine:
Technical Parameters:
Applicable Cable Diameter: 9mm to 36mm
Applicable Conduit Outer Diameter: 25mm to 63mm
Working Pressure: 12 bar to 15 bar
Pushing Distance: The machine can push the cable continuously for a length of 1000 to 2000 meters, or even longer. However, it is recommended to plan for a single blowing distance of around 1500 meters.
Accessory Options:
Air Cooling System: Improves the effectiveness of cable blowing, especially suitable for hot climates.
Cable Traction Head: Increases pulling force by approximately 10%, suitable for thinner and softer cables, thereby enhancing the cable blowing effect.
Y-Type Connector: Used to install a second or third cable within an existing cable conduit or to simultaneously install two cables in the same conduit.
Air Blowing Lubricant: A type of pipeline lubricant, also known as cable-blowing oil, that enhances the speed and distance of cable installation.
By selecting appropriate accessories, the efficiency and applicability of the cable-blowing machine can be improved, reducing the difficulty of cable installation. This helps to minimize infrastructure and labor costs while increasing the daily cable installation capacity.
It is essential to note that during the use of a cable-blowing machine for cable installation, operators must prioritize safety, ensure the compatibility of the equipment and conduit, and avoid damaging the cables and the machine. Additionally, when choosing accessories such as air blowing lubricants, it is crucial to make rational selections based on practical situations and requirements.
