The Draw-in System involves laying empty pipes or ducts made from materials like concrete or PVC in a trench, with manholes or access points at intervals. The cables are then pulled or "drawn in" through these ducts. This method is often referred to as a conduit or duct bank installation.

• Advantages: This system offers superior mechanical protection and allows for easy repair, replacement, or addition of new cables without the need for extensive excavation, making it ideal for urban areas with high traffic and existing infrastructure.

• Disadvantages: The initial installation cost is significantly higher due to the materials and labor required for the duct bank construction. Heat dissipation is also less effective compared to direct laying, which may reduce the cable's current-carrying capacity.
