Relco Electricals India Private Limited

We are the manufacturers of the Discharge/Earthing Pole Assembly for Conventional and High Rise 25kV AC traction overhead equipment, switching station and substations as latest RDSO specifications.

The Discharge/Earthing Pole is intended for outdoor use and meant for discharging and earthing the 25kV AC traction overhead line and concerned equipment of the switching station or substation after the line/equipment is isolated from the source or supply, before the commencement of any maintenance work on them, and to drain to earth induced voltages from an adjacent line/equipment charged at 25kV, 50Hz ac. It also conducts short circuit current of upto 6250Amps for 1 second without any damage to it in the event of accidental charging of the earthed line or accidental connection of the Discharge/Earthing Pole assembly to a live line.

In the electric power distribution industry, a hot stick is an insulated pole, usually made of fiberglass, used by electric utility workers when engaged on live-line working on energized high-voltage electric power lines, to protect them from electric shock. Depending on the tool attached to the end of the hot stick, it is possible to test for voltage, tighten nuts and bolts, apply tie wires (twisted lengths of ductile wire which fasten the running cable to its supporting insulators), open and close switches, replace fuses, lay insulating sleeves on wires, and perform various other tasks while not exposing the crew to a large risk of electric shock.

Hot sticks are made in different lengths, from simple 3-foot (1 m) sticks to 30-foot (9 m) telescoping models. Because the fiberglass provides electrical insulation, the hot stick allows utility workers to perform operations on power lines safely without de-energizing them or while the state of the power line is not yet known. This is essential because certain operations (such as opening or closing combination fuse/switches) must occasionally be performed on an energized line. Additionally, after a fault occurs, the exact state of a line may not be certain; in this case, for reasons of crew safety, the utility workers must treat the line as though it were energized until it can be proven that it is not and safety ground cables can be applied to the line (so that the line is guaranteed to remain grounded/earthed while maintenance is performed upon it). If power tools are fitted to the end of the hot stick, they are usually powered hydraulically rather than electrically because, like the fiberglass of the hot stick, the hydraulic fluid is also a good insulator. The hydraulic power is commonly supplied from the bucket truck (cherry picker or aerial work platform) supporting the workers.

The hot stick not only electrically insulates the worker from the energized conductor, it provides physical separation from the device being operated, to reduce the chances of burns which might result from electrical arcing if there is a malfunction of the device being operated.

Earthing Discharge Rods an insulated rod, usually made of strong fiberglass tubes with extension handles. Discharge Rod complete with accessories suitable for 11KV, 33KV, and 66KV system voltage for discharging dead conductors/busbars. A discharge rod is a safety equipment used to ensure safety.

A rescue rod, also known as a rescue hook or rescue pole, is a specialized tool used primarily in emergency situations to safely remove or assist individuals who are in hazardous or hard-to-reach locations. These rods are designed to provide a means of reaching and securely grasping a person from a distance, avoiding direct physical contact which could be unsafe or impractical. Here's a detailed explanation of rescue rods:

Components and Construction

1. Materials:
   • Pole: Typically made of lightweight and durable materials such as fiberglass, aluminium, or composite materials.
   • Hook: Made of strong materials like steel or aluminium alloy, designed to securely grasp clothing, harnesses, or other rescue equipment.
   • Handle: Often insulated or ergonomically designed for a secure grip, even in wet or slippery conditions.
2. Design:
   • Telescopic or Extendable: Many rescue rods are telescopic, allowing them to be extended to reach varying distances, typically ranging from a few feet to several meters.
   • Non-Conductive: Especially important for rescue rods used in electrical or high-voltage environments, where insulation prevents electrical conductivity and minimizes the risk of electric shock.
   • Lightweight and Portable: Designed for ease of transport and deployment during emergency response situations.

Functions and Uses

1. Emergency Rescue Operations:
   • Confined Spaces: Used to extract individuals trapped in confined spaces such as trenches, collapsed buildings, or industrial equipment.
   • Water Rescue: Employed to reach and retrieve individuals in water bodies, where direct access is limited or dangerous.
   • Electrical Hazards: Specifically designed non-conductive rescue rods are used to safely assist individuals near live electrical equipment or power lines.
2. Safety and Efficiency:
   • Minimize Risk: Enables rescuers to maintain a safe distance from hazardous conditions while performing extraction operations.
   • Versatility: Can be used in various rescue scenarios, adapting to different environments and conditions.
3. Accessibility:
   • Reach: Provides extended reach capabilities, allowing rescuers to access individuals in areas that are otherwise difficult or dangerous to approach.
   • Precision: The hook or gripping mechanism is designed for precise control and secure handling of the person being rescued, ensuring minimal risk of injury during extraction.

Operation and Deployment

1. Deployment:
   • Quick Deployment: Designed for rapid deployment in emergency situations, with easy access and assembly.
   • Telescopic Extension: Extendable sections allow rescuers to adjust the length of the rod as needed to reach the rescue target.
2. Handling:
   • Grip: The handle is ergonomically designed for a secure and comfortable grip, providing control during delicate rescue operations.
   • Operation: Rescuers are trained in the proper use of rescue rods, including techniques for approaching, hooking, and safely extracting individuals from hazardous environments.

Why to use Discharge Rod?
A discharge rod is a necesarry equipment when it comes to safety while live working(maintenance work in electrical distribution and transmission systems).
After shutdown and disconnecting the Air Break Switches there still might be either residual current in the line due to presence of transformer and other electrical equipments or due to reverse current or back current from home appliances like generator or invertor or leakage current numerous reasons.
Due to the above reasons it is still not safe to work on the electric line.
Residual current, reverse current and leakage current is present in lines even after shut down.
To protect ourselves from current we use a device which we call as Discharge Rod.

What is Earth Discharge Rod/Discharging Rod/ Earthing Rod?
Discharge Rod is a safety device which is used to discharge a bare conductor. That is to remove electrostatic charge from a Disconnected Circuit.

Parts of Discharge Rod

• Top End: The top end of the discharge rod consists of a clamp which is made of robust cast aluminum which is generally called alligator clamp. The clamp consists of extra holes to that Earth wire and other live working equipment like high voltage detectors can be attached to it. You can also find a copper hook instead of cast aluminum clamp.
• Highly insulated Rod: The top end clamp is connected to a rod. This rod is highly insulated generally made of FRP Material (Fiber Reinforced Plastic). This rod also has rubber grip on it. Length of rod can be adjusted as per use from 6 feet to 18 feet.
• Earth Wire: A copper wire is connected to the top end clamp for earthing purposes. For 11kV and 33kV Discharge Rod 6 sq mm ISI marked copper wire is used. Normally the size of copper wire used for earthing ranges from 6 sq. mm to 10 sq. mm. The length of earth wire is 10 meter or can be ordered as per requirement.

Where to use Discharge Rod?
While working on a pole in a circuit, after closing the feeder line and operating the Air Break in open position, connect the discharge rod on the output side of the transformer and on the line subsequent to the pole where the work needs to be done.
