4 core 25 mm² STA Armoured Cable, also referred to as STA or Armoured Cable, are multi-core power cables which have a layer of steel wire armour. The armour offers mechanical protection enabling the cable to stand up to higher stresses, be buried directly, and can be used in internal, external and underground projects. It is mainly used for industrial wiring and mains distribution.Cables are manufactured with several different layers and elements. The main components of STA cable is the:
Conductor. The conductor is usually several cores of plain stranded copper.
Insulation. The Insulation is used to protect the conductors from any water damage, especially if the cable is buried underground. It also offers a barricade between the conductors and the other metal components, including the armour.
Bedding. The PVC bedding serves as a buffer between the inner live component of the cable and the outer components.
Steel tape Armour. The Steel tape Armour itself is placed over the bedding, providing the cable protection from stress. Sometimes, the armour can be used as the earth cable.
Cable sheathing. The cable sheath is used to protect the inner components of the cable and supplies more protection from mechanical harm and stress.
Due to above 4 core 25 mm² STA armoured cable’s structure,which has many advantages,as follow:
1. Safety
The 4 core 25 mm² armoured cables are designed to give added safety benefits. The armor layer acts as an extra layer of insulation, reducing the danger of electrical shock and fire hazards. Normal cables do not offer this added safety feature.
2. Longevity and Durability
Due to their sturdy construction, armoured cables have an extended life span compared to standard cables. They are less prone to harm, reducing the need for constant repairs or replacements. This aspect contributes to long-term cost savings.
3. Resistant to extreme weather
It’s also created to withstand harsh climate condition. Rain, snow, or extreme temperatures, it can deal with it all without losing its effectiveness.

4 core 25 mm² STA armoured cable is a cable with strong resistance to drawing and crushing, and it can adapt to any extreme environment. Steel wire armor has strong flexible strength and can be utilized for laying directly buried cables or basic threading pipes, general roads, tunnel construction, etc, while steel tape armor has strong extrusion resistance and is appropriate for the overhead or vertical laying of short-circuit lines.
Adding a metal-clad armor protective layer to the cable can prolong the life span of the cable, enhance the anti-interference ability of the cable through shielding protection, strengthen the anti-corrosion ability of the cable, and stop mice from biting.
Due to above 4 core 25 mm² STA armoured cable’s structure,which has many applications,as follow:
1. Data Centers
The crucial nature of data centers demands reliable power infrastructure. Armoured electrical cables offer the durability and protection needed to preserve uninterrupted power supply, safeguarding the integrity of data storage and processing.
2. Renewable Energy Projects
Sta armoured cable play a crucial role in connecting renewable resource sources to the power grid. Whether it’s a solar farm or a wind energy project, these cables offer the necessary infrastructure to transfer the produced electricity efficiently and securely.
3. Marine Applications
The marine industry depends on armoured cable to deliver power on ships and offshore platforms. The cables’ ability to resist water ingress and withstand destructive marine environments makes them a necessary component in maritime applications.
Managing and setting up 4 core 25 mm² STA armoured cables require a level of caution to uphold safety. Prior to setup, guarantee the cable is suitable for its intended use, considering factors like the environment, the nature of the application, and the cable’s rated temperature and voltage.During installation, prevent twisting or bending the cable beyond its minimal bending radius. Excessive bending can destroy the armour and compromise its effectiveness.
Remember that the ends of the metallic armour can be sharp. Handle with care to prevent injuries. Use of suitable protective gear, like gloves, can be highly advantageous in this regard.A routine visual inspection can also help spot potential issues early. Always check for signs of damage or exposed wires before working with armoured cables. Damaged cables should be repaired or replaced immediately.
