A Legacy of Service

CEPCO began 45 years ago with a small team of highly skilled technicians specializing in cable jointing, termination, and pulling. Over the years, our team has expanded in both size and expertise, now covering high-voltage on-site cable testing, transformer testing, cable fault location, civil works, horizontal directional drilling, and more.

Our Service

Horizontal Directional Drilling (HDD)

CEPCO is a specialist in underground horizontal directional drilling (HDD) using advanced TERRA and DITCH WITCH machinery. With 8 experienced crews, we provide non-disruptive solutions for road crossings, ideal for installing water, gas, electric, fiber optic, and telephone cables. Our capabilities include drilling HDPE pipes from 90 mm to 630 mm in diameter and lengths of up to 300 meters.
