Why MVCC? The Technology Behind the Project

MVCC technology involves using conductors insulated with a durable, UV-resistant XLPE (cross-linked polyethylene) covering that provides multiple benefits over traditional bare conductors. The conductor core is made of stranded aluminium alloy, ensuring high conductivity and mechanical strength, while the insulation offers protection against environmental factors such as moisture, corrosion, and physical contact.

This technology is especially suited for coastal regions like Jamnagar, where humid and saline conditions accelerate corrosion in bare conductors. The MVCC’s protective covering significantly extends the conductor’s lifespan by preventing corrosion and mechanical damage.

Key Benefits of the Jamnagar MVCC Project

• Enhanced Safety: The covered conductor reduces the risk of electrical accidents by insulating live wires, protecting both the public and utility workers. In case a conductor falls, the insulation prevents direct contact with the live wire, reducing hazards in densely populated and roadside areas.
• Reduced Power Losses and Improved Efficiency: The MVCC design minimises electrical losses due to better conductivity and insulation, contributing to energy efficiency and reduced operational costs. This is critical in a coastal area where power reliability is essential.
• Environmental Protection: By reducing the need for extensive tree trimming and vegetation clearance, MVCC indirectly helps preserve local flora and fauna. Additionally, the project supports wildlife protection by preventing faults caused by contact with animals or birds, which is vital in ecologically sensitive zones.
• Corrosion Resistance: The XLPE insulation provides excellent protection against moisture and salt-laden air, common in coastal climates, thus preventing corrosion-related failures and ensuring long-term reliability.
• Operational Advantages: The project faced challenges such as narrow roads, congested urban areas, and limited shutdown windows due to regular traffic. Despite these, the use of MVCC allowed for compact installation with reduced right-of-way requirements, making it feasible to upgrade the network without extensive infrastructure changes.

Impact on PGVCL’s Power Distribution Network

This reconductoring project enhances the reliability and safety of PGVCL’s 11 kV distribution network, reducing outages caused by environmental factors like storms and vegetation contact. It also contributes to the coastal area’s infrastructure development by minimising power losses and supporting sustainable energy distribution.
