The SAPSONS Hydraulic Cable Spiking Tool is a specialized electrical safety device used to confirm that a power cable is completely de-energized before any maintenance or repair work is carried out.
Description :
The SAPSONS Hydraulic Cable Spiking Tool is designed for low-voltage (LV) and medium-voltage (MV) power cables to ensure the absence of electrical current, thereby protecting technicians from accidental electric shock or arc faults.
It works by mechanically piercing (spiking) the cable using a hardened chisel driven by hydraulic force. If the cable is still live, the act of spiking will cause a controlled fault, indicating the presence of voltage—thus preventing unsafe cutting.
⚙️ How It Works
1. The tool is positioned around the cable.
2. The operator activates the hydraulic system (often from a safe distance).
3. The spike is driven through the cable.
4. If the cable is live, a fault occurs and protection systems trip.
5. If no reaction occurs, the cable is confirmed de-energized.
Construction & Components :
The tool has a robust and reliable hydraulic design, consisting of:
• A hand-operated hydraulic pump
• A hydraulic cylinder connected via hose
• A hardened alloy steel chisel attached to the piston
• A rectangular tubular steel frame for mounting on the cable
• Clamping mechanism with threaded rods for firm positioning
• A separate earthing cable (~6 m) with earthing rod for grounding safety
Working Principle :
1. The tool is securely clamped onto the cable.
2. The hydraulic pump is operated manually.
3. Hydraulic pressure drives the chisel into the cable.
4. The chisel penetrates the sheath, insulation, and reaches the conductor.
5. This confirms whether the cable is live or dead before cutting or jointing.
Purpose & Applications :
• Ensures electrical safety before maintenance
• Used during cable repair, jointing, and termination
• Mandatory safety step for 11 kV / 33 kV cable systems
• Prevents accidents caused by mistakenly cutting live cables
Key Features :
• Hydraulic operation for controlled force
• High-strength chisel for effective penetration
• Safe grounding arrangement
• Heavy-duty construction for field use
• Simple and reliable operation
The SAPSONS Hydraulic Cable Spiking Tool is a safety device used in electrical maintenance to confirm that a power cable is completely de-energized before work begins, thereby significantly reducing the risk of electrical accidents.
The tool is mainly used for low and medium voltage cables during activities like repair, jointing, and termination, preventing accidents caused by cutting live cables.
A Hydraulic Cable Spiking Tool is a critical safety instrument used in high-voltage electrical environments. It ensures worker safety by positively identifying dead cables before cutting, using a controlled and remote-operated spiking mechanism. It is widely used by utility companies, electrical contractors, and maintenance teams to prevent accidents and ensure safe cable handling.
Overall, it is a robust, reliable, and essential safety tool that protects electrical workers by ensuring safe working conditions.
