What is Maintenance Free Earthing?
Earthing, also known as grounding, is the practice of transferring electrical charges to the ground through low-resistance cables or rods to quickly discharge any stored energy. There are two main types of earthing: maintenance-free earthing and
Read MoreSmart Meters in India ─ Types & Application
Smart meters record information on electrical energy consumption, voltage levels, current and power factors. They offer greater clarity on this information to the electrical service providers regarding electrical consumption, help with monitoring the system, and billing. They use advanced metering infrastructure (AMI) that differs from automatic meter reading (AMR.). They …
Cable Glands ─ Need for Electrical Equipment and Switchgears
Cable Gland is the ‘mechanical cable entry device’ attached to the end of electrical cables and secures them to any piece of equipment. They are also commonly known as cable connectors, cable fittings, cord grips, or cable strain reliefs. Cable Glands are vital for terminating cables in harsh or hazardous …
Installation of Cable Lugs
Cable lugs are electrical components used to safely connect wires and cable terminals to electrical equipment or terminate them. They are designed to easily and securely connect and disconnect electrical joints permanently or for maintenance. There are different types of cable lugs available for various electrical applications. They are essential …
Distribution Boxes: Types and Functions
The distribution box serves as the load centre and distributor of electrical power. A distribution box ensures that electrical supply is distributed in the building, also known as a distribution board, panel board, breaker panel, or electric panel. It is the central electrical supply system of any building or property. …
Bimetallic Lugs & Solution for Solar Industry
The solar industry is one of the most flourishing sectors in India. Electricity production using solar energy is getting much cheaper and easy. The bimetallic solutions like bimetallic lugs & joints are playing a crucial role here. In this article, we will discuss how bimetallic solutions are becoming the norm …
Earthing for a Distribution or Transmission Line
Earthing is an important part of electrical distribution lines. Installation of a protective grounding on the power line structure creates a safe work zone. It neutralises leakages or short-circuit current and offers a simple and easy path for the current to the earth with zero damage potential. Importance of Earthing …
What is Substation Earthing? [Explained with Calculations]
The fundamental role of any substation earthing is to dissipate the short circuit current into the earth without drying out the area and to limit the potential gradient throughout the substation to maintain the step and touch voltages within safe values. There are two features considered during the design of …

Follow us on LinkedIn for regular updates on our Earthing and Lightning Protection Products! Cable lugs help in the easy installation of cable termination and aid in the repair and maintenance of electrical devices or cables. Commonly, the lugs are used to connect one cable with another or to connect …
Earthing & Lightning Protection System for Substations
In an electrical substation, Lightning Protection System is important for the smooth operation of electrical networks during lighting strikes. Lightning strikes can cause severe damages due to the surge of extra voltage during a strike that is injected into a transformer. As a result, a strike and switching can cause …
