PLC Power Cables LV/MV/HV – Comprehensive Energy Transmission Solutions

Power Lines Contracting Company (PLC) began its journey in 2003. Since then, it has aimed to become a top turnkey provider in Saudi Arabia. Over the years, PLC has built a strong reputation as both a reliable contractor and a trusted materials stockist. As a result, we now proudly deliver premium Power Cables. These include low (LV), medium (MV), and high voltage (HV) options suitable for various industries. These sectors include utility, oil and gas, petrochemical, and communications.

End-to-End Engineering and Quality Control

Our Power Cables offering includes full project quality control from planning through execution. We develop tailored quality plans, follow strict HSE procedures, and monitor progress with industry-standard tools. Our experienced team delivers structured route investigations, thermal resistivity testing, trial pit reporting, and EXCEL‑based progress charts for transparent tracking.

Detailed Design & Route Planning

To ensure reliable cable performance, we begin by designing precise route drawings, joint bay layouts, and road-crossing plans. Additionally, our engineers assess uplift pressures affecting HV cables in shallow groundwater areas. Based on these findings, we create duct bank protections that effectively shield against subsurface stresses. Moreover, we develop structural designs for joint bays, fiber splice pits, and PD sensor pits. These enhancements help keep Power Cables installations safe, long-lasting, and fully compliant with industry standards.

Thermal and Soil Analysis

We conduct soil sampling and thermal resistivity analyses to determine optimal backfill mixes. Our designs for thermal backfill ensure proper heat dissipation for Power Cables, especially in demanding environments. We also estimate cut‑and‑fill volumes and design bunds to protect cable trenches or duct banks along the route.

Substation and AC Mitigation Studies

Inside substations, our team actively designs support structures, core openings, and entry ducts. These components ensure smooth and reliable cable integration. Moreover, we conduct AC mitigation studies at pipeline crossings. These studies help prevent corrosion and electrical interference. To enhance safety, we also design earthing and cathodic protection systems, ensuring grounded performance for all Power Cables installations.

Installation, Jointing, and Testing

Our team excels in EHV/HV cable jointing and terminations. We perform all electrical testing, including resonant frequency AC tests, partial discharge measurements, and full commissioning. We also install Distributed Temperature Sensing (DTS) systems, supporting continuous health monitoring of Power Cables under high-load operation.

Fiber Optic and Communication Cabling

Beyond power conductors, PLC installs and tests fiber-optic and metallic communication cables. We handle fusion splicing, OTDR testing, air‑blown installations, and commissioning to support control, monitoring, and data-transmission needs alongside power infrastructure.
