A quotation for a high-voltage (HV) cable laying project will be substantially higher than for a low-voltage (LV) project due to increased complexity, material costs, and safety requirements.

• HV Projects: These require specialized, thicker, and more expensive cables, along with dedicated protective ducts and specific bedding materials to manage thermal dissipation. The labor for HV projects must be performed by highly certified technicians using advanced, tension-controlled equipment. The depth of burial and safety standards are more stringent, which adds to excavation and reinstatement costs.

• LV Projects: These projects typically use standard cables and conduits. The installation depth is shallower, and while safety is still paramount, the overall project complexity and equipment requirements are less demanding. The associated labor and material costs are, therefore, considerably lower.
