FAQ

What is the purpose of a metallic shield in MV and HV cables?

Why do cable prices vary significantly among suppliers within the same region?

How do you calculate the minimum bending radius of cables?

What is the minimum order quantity for the product?

Is a flame-retardant cable also fire resistant?

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.

Flame Retardant Cables VS Fire Resistant Cables?

Both types of cables are crucial in enhancing the likelihood of escape and survival in the event of a fire and are often confused with one another. However, there is a fundamental distinction between flame retardant cables and fire resistant cables. Flame retardant cables are engineered to inhibit the spread of fire to adjacent areas. On the other hand, fire resistant cables are specifically designed to preserve circuit integrity and ensure functionality during a fire, under specified conditions, aiding both evacuees and firefighters.

How Do Water-Blocking Cables Work?

Water-blocking cables are essential for ensuring reliable operation in environments with high levels of moisture or frequent water contact. These cables employ water-blocking techniques to effectively prevent water ingress, protecting them from damage and prolonging their lifespan.

What are the benefits of EPR material?

EPR is widely used as an insulation material for electric cables due to its high dielectric strength, and it also serves as a sheathing material with excellent ozone and weathering resistance. EPR has a wide thermal range, typically spanning from -55°C to 150°C. Unlike other organic rubbers, there is no need to tin the copper conductor to prevent deterioration of the rubber.

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.
