Armored vs. Unarmored Cables?

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.

Longitudinal Water Blocking vs. Lateral Water Blocking?

A longitudinally water blocking cable is designed with a barrier to prevent the spread of moisture along its length. Longitudinal water blocking stops water from migrating along the cable's core, typically between the conductor strands, insulation layers, or metallic screens. Lateral water blocking ensures that water cannot penetrate the cable in the event that the sheathing is pierced or damaged. Radial water blocking prevents water from penetrating the cable's outer sheath or insulation layers, thereby stopping it from entering the cable structure entirely. Longitudinal water blocking can be achieved through various methods, including the application of water-blocking tapes and powders. These are frequently located on either side of a metallic screen and conductor. Lateral water blocking is typically accomplished by applying a layer of aluminum/polyester tape to the underside of the outer sheath.

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 minimum order quantity for the product?

The minimum order quantity for low and medium voltage cables is 200 meters, whereas for high voltage cables, it is 2000 meters. Should the order quantity fall below the MOQ, however, if the factory has stock, we can still supply it.

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.
