FAQ
Q1: What does "CU/Silicone/Silicone/SWA/Silicone" mean?
A: This describes the cable construction layer by layer: CU (Copper conductor), Silicone (core insulation), Silicone (inner bedding/sheath), SWA (Steel Wire Armor), and Silicone (outer sheath).
Q2: Why use silicone insulation instead of PVC or XLPE for mining cables?
A: Silicone offers superior flexibility in extreme cold, higher temperature resistance (up to 180°C), and better flame retardancy—critical properties for demanding mining environments where cables flex constantly and may encounter heat.
Q3: Is this 4x35mm² cable suitable for connecting mobile mining equipment?
A: Yes. The flexible stranded copper conductors and pliable silicone construction, combined with SWA for mechanical protection, make it ideal for semi-static or limited-flex applications like powering mobile crushers, pumps, and temporary substations.
Q4: What voltage rating does this cable typically support?
A: While construction supports various voltages, this design is commonly rated for 0.6/1kV for low-voltage distribution. Higher voltage ratings can be engineered upon request.
Q5: Can this cable be directly buried or installed in wet conditions?
A: The robust SWA and silicone outer sheath provide excellent moisture resistance, but for direct burial, we recommend consulting our engineers regarding additional waterproofing measures or specialized bedding compounds.
