Armored vs. Unarmored Cables?
Armored cables are ideal for direct burial and laying underground, offering protection against environmental factors. Unarmored cables are unsuitable for burial or use in other challenging applications and installations.
-
Why do cable prices vary significantly among suppliers within the same region?
Cable prices vary due to differences in supplier strategies, competition, raw materials, and production processes, as well as after-sales services, including installation, equipment, and ongoing support.
-
What is the operating temperature of the cable?
The operating temperature of a cable is determined by the insulation and sheathing material. PVC has a range of -15°C to 70°C, XLPE can reach up to 90°C, while silicone rubber can handle temperatures from -60°C to 180°C.
-
Is a flame-retardant cable also fire resistant?
No. A flame-retardant cable is not the same as a fire-resistant cable. A flame-retardant cable is designed to restrict the spread of fire by inhibiting combustion. Fire-resistant cables, on the other hand, maintain circuit integrity and continue to function for a specified time under defined fire conditions.
-
What is the length tolerance for cables?
The tolerance for the power cable is 0 to +0.5%. For the bare conductor, the tolerance is ±5%.
