Armored cables have an additional layer of protection compared to ordinary cables to protect them from damage from squeezing, crushing, scratching, and rat bites. This additional layer of armor is undoubtedly more expensive. While armored cables are undeniably more expensive than ordinary cables, choosing armored cables is a good option for high efficiency. Today, we'll explain why copper-core armored cables are more expensive than ordinary cables.
Reasons Why Copper-Core Armored Cables Are More Expensive Than Ordinary Cables
1. Armored cables are typically laid underground because their armor is not white. When buried in trenches, they protect against vehicle pressure, rat bites, and rock scratches, which is why armored cables are often used. If problems arise with cables laid underground, the cost is significant, time-consuming, and labor-intensive.
2. The mechanical protection of armored cables can be added to any cable structure to enhance its mechanical strength and corrosion resistance. This is a telephone cable designed for areas susceptible to mechanical damage and erosion. They can be laid in any manner and are particularly suitable for direct burial in rocky areas.
3. Among ordinary power cables, armored cables have a higher market price than unarmored cables because they have a higher protective layer than unarmored cables, protecting them from external mechanical damage, chemical corrosion, and other factors. Naturally, this leads to a higher price. However, armored power cables are generally used in high-rise buildings and are generally not required for indoor locations.

1. The former is suitable for transmission lines in applications such as automatic control or monitoring systems with an AC rated voltage of 450/750V and below, and for connecting electrical instruments.
2. The latter is suitable for power lines with a rated voltage (U0/U) of 3.6/6 to 26/35kV for power transmission and distribution.
Armored copper-core cables are cables with a layer of steel armor beneath the outer insulation. Low-voltage cables are mostly made of iron, while high-voltage cables can be made of iron, stainless steel, or other materials. They are used to protect cables from external damage when buried underground, but are not the same as fuses. Therefore, this is the main reason why armored cables are more expensive. We all know that the use of wires and cables in some harsh environments will affect their service life. At this time, cables with special performance are needed to adapt to such places, so this type of cable will be used. When buying wires and cables, do not give up on choosing them just because they are expensive. These products are worth the money, and there is a reason for their high price.
