The DB-60 20 mm conduit is made from the best rigid PVC materials. Its main advantages are mechanical strength, corrosion resistance, and environmental durability for low-voltage, medium-voltage, and telecommunication cabling. The conduit is very suitable for direct burial without encasement, thus giving an advantage of quick installation and cost-effective underground wiring solutions.

The PVC Type DB-60 Conduit – 20 mm (½″) is a direct burial rigid PVC conduit engineered to protect underground electrical and telecommunication cabling. “DB” refers to Direct Burial, meaning it is designed for installation directly in soil without additional encasement.

The DB-60 classification ensures a minimum wall thickness capable of withstanding soil pressure, mechanical loads, and environmental stress, making it suitable for residential, commercial, and light industrial projects. The 20 mm (½″) nominal diameter is ideal for low-voltage power, communication, and control cabling, offering a balance between cable capacity and ease of installation

Why Choose Direct Burial Conduits?

Burial conduits of the like DB-60, for instance, come with a number of favorable aspects for electrical installations underground:

- Installation made easier: There is no concrete encasement required, which leads to less labor and a quicker project time.

- Cost-saving: The overlooking of the use of additional materials- sand bedding or reinforced concrete.

- Protection against mechanical causes: Cables are guarded against soil pressure, water, as well as smallimpact.

- The possibility of taking further steps to the future: Extra cable runs or replacements are done without a great deal of excavation.

- PVC brings about a very durable and long serviceable conduit which lasts 30-50 years even in normal conditions.

DB-60 conduits are a perfect match for Gulf infrastructure projects in areas of residential neighborhoods, commercial complexes, street lighting networks, and low-load industrial applications.
