HDD (Horizontal Directional Drilling) causes virtually no surface disruption and is ideal in urban/road crossings – it can hit 0.3 m depth and pull long segments (suitable for ~33 kV and fiber networks). Vibratory ploughing is much faster (10+ km/day) but requires open corridors – best for rural or substation feeder lines. Both methods use powerful winches and specialized grips: HDD won’t disrupt traffic or landscaping, whereas ploughing is quicker and cheaper if land is available.
