Design and Consultancy

Transmission Line/Substation/Distribution Network

Polite Powertech Pvt. Ltd. offers specialized engineering services for the design of Extra High Voltage (EHV) cable systems, ensuring safe, reliable, and efficient transmission of electrical power. A critical aspect of our EHV cable system design is the calculation of induced voltage in cable sheaths and the design of effective cross-bonding schemes to mitigate sheath voltage and losses.

Our design services include:

• Electrical and thermal analysis of cable systems
• Induced voltage calculations in metallic sheaths
• Design of appropriate cross-bonding and earthing systems
• Optimization of cable routing to minimize electromagnetic interference and system losses
• Compliance with IEC, IS, and utility-specific standards

With our deep technical expertise and use of advanced simulation tools, we ensure that EHV cable systems are designed to deliver maximum reliability, safety, and performance, even in the most demanding environments.
