FAQ

Is a flame-retardant cable also fire resistant?

How long is the validity period of cold shrink cable accessories?

What is the length tolerance for cables?

What temperature can high-temperature resistant cables reach, and what are their application scenarios?

What is the validity period for the offer of cable?

What is the service life of cables?

The design life of power cables is typically 20 to 30 years; however, this can vary significantly based on factors such as installation, environmental conditions, and the quality of the cable.

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.

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.

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.
