4 Core 16 sqmm Stranded Copper Cable 600/1000V, STA Armored, PVC Insulated (Red, Yellow, Blue, Black) | Riyadh Cables Group

Precise Technical Specifications for Riyadh 4x16 CU/XLPE/STA Armored Cable

The Riyadh 4x16 CU/XLPE/STA armored cable is not merely a connecting wire; it is an integrated protection system designed to withstand harsh conditions in the Kingdom of Saudi Arabia. The conductor consists of high-purity stranded copper, ensuring efficient current transmission up to 100% without energy loss. What distinguishes this cable from competitors is the use of XLPE (Cross-Linked Polyethylene) insulation instead of traditional PVC. This insulation withstands operating temperatures up to 90°C, which is essential in Riyadh, where buried cables or those in exposed areas may overheat due to scorching sunlight exceeding 50°C.

The armored structure relies on a double steel tape (STA) wrapped around the insulation. This tape provides immense mechanical strength, protecting the cable from the weight of soil during direct burial or pressure from heavy trucks passing on temporary roads. The outer PVC sheath adds an additional layer of protection against chemical corrosion and salts present in the desert environment.

Why Choose XLPE Insulation in the Riyadh Climate?

When comparing XLPE insulation to traditional PVC, the difference becomes clear under thermal loads. In 2026 construction projects, we observe that XLPE cables retain their insulating properties even with high current flow, whereas PVC tends to soften and lose insulation integrity. If you intend to use the cable in areas exposed to direct sunlight or under moist soil, choosing the Riyadh 4x16 CU/XLPE/STA armored cable is the correct engineering choice to ensure a service life exceeding 25 years.

Frequently Asked Questions About XLPE Armored Cable

Is it allowed to bury an XLPE armored cable directly in the soil?
Yes, the Riyadh 4x16 CU/XLPE/STA armored cable is considered safe for direct burial in most soils, but it is recommended to cover the burial area with a thin layer of sand to protect the outer sheath from sharp gravel.

What is the difference between a 4x16 copper armored and non-armored cable?
The non-armored (mechanically unprotected) cable relies solely on plastic sheathing, making it susceptible to mechanical damage. The armored cable contains a steel tape that provides high resistance to tension and pressure, making it ideal for outdoor installations and infrastructure.

Is the price of an XLPE armored cable higher than PVC?
Yes, the price of electrical cables in Riyadh for XLPE armored cables is slightly higher due to the cost of advanced insulation material, but the return on investment is higher due to its long lifespan and reduced network failures.
