The common structure of an 4 core 50 mm² STA armoured cable can be broken down as follows:
Conductor: includes plain stranded copper (cables are categorized to suggest the degree of flexibility. Class 2 describes stiff stranded copper conductors as stipulated by British Standard BS EN 60228:2005).
Insulation: Cross-linked polyethylene (XLPE) is used in a variety of power cables because it has good water resistance and excellent electrical properties. Insulation in cables guarantees that conductors and other metal substances do not enter into contact with each other.
Bedding: Polyvinyl chloride (PVC) bedding is used to supply a defensive border between inner and outer layers of the cable.
Armour: Steel tape armour provides mechanical protection, which implies the cable can stand up to higher tensions, be buried directly and used in external or underground projects.
The armouring is normally connected to earth and can sometimes be used as the circuit protective conductor (” earth wire”) for the equipment supplied by cable.
Sheath: a black PVC sheath holds all elements of the cable together and provides additional protection from external stresses.
The PVC version of STA cable, described above, satisfies the requirements of both British Standard BS5467 and International Electrotechnical Commission standard IEC 60502.It is known as SWA BS5467 Cable and it has a voltage rating of 600/1000V.STA cable can be described more typically as mains cable, armoured cable, power cable and brochure armoured cable. The name power cable, however, applies to a wide variety of cables including 6381Y, NYCY, NYY-J and 6491X Cable.
Due to above 4 core 50 mm² STA armoured cable’s structure,the following are some benefits of sta armoured cable:
1. Flexibility and Adaptability
Another unique advantage of 4 core 50 mm² STA armoured cable glands is their versatility. They are available in various sizes and configurations, allowing for compatibility with a wide range of cable types and diameters. This adaptability is vital in circumstances where different cables need to be connected, guaranteeing a seamless and secure fit.Furthermore, armoured cable glands are developed to accommodate both armored and non-armored cables. This flexibility simplifies installation processes and decreases the need for multiple kinds of glands, streamlining inventory management.
2. Enhanced Safety Standards
Safety is vital in any electrical installation, and sta armoured cable glands play a critical role in upholding these standards. Their robust design guarantees that cables remain securely connected, decreasing the risk of accidental disconnection or exposure. Furthermore, many armoured cable glands are equipped with features such as locking mechanisms and strain relief, further enhancing safety.In harmful areas where the potential for explosive atmospheres presents, specialized sta armoured cable glands with explosion-proof certifications are available. These glands are meticulously engineered to include any sparks or flames within the enclosure, preventing catastrophic incidents.
3. Effective Strain Relief
Cables are subjected to mechanical stresses, especially in industrial environments where they may be exposed to resonances or movements. Armoured cable glands excel in offering effective pressure relief for cables, avoiding them from being pulled or twisted. This not only prolongs the life of the cables but also minimizes the risk of damage that can lead to costly downtime.

The purpose of 4 core 50 mm² STA armoured cable is to enhance the cable’s mechanical strength and improve the anti-erosion ability. The commonly used armor materials are steel tape, steel wire, and aluminum tape. The steel tape and steel wire armor layer have high permeability and an excellent magnetic shielding impact, resisting low-frequency obstruction.It is a special cable designed for the area which is prone to mechanical damage and erosion.
4 core steel tape armored cable is made of difficult steel wire conductor placed with an insulation layer. Steel wire armoured cable is generally used in engineering, metallurgy, machinery manufacturing, construction and more. The mechanical protection layer of the armoured cable can be added to any structure of the cable to increase the mechanical strength of the cable and improve the anti-erosion chance, which appropriates for the bad environment, and the steel wire to protect the conductor and insulation.
Due to above 4 core 50 mm² STA armoured cable’s structure,which has many applications,as follow:
1.Utilized in transformer stations, switching blocks, in electric power plants and industrial plants. Low voltage power cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical tension and tensile strain.
2.To prevent the effects of external impact, the adhering semi-conductive layer extruded between conductor and insulation, together with concentric copper conductor, safeguards constraint of electric area and resistance to partial discharges.
3. Because of its very low element of dielectric decrease, which remains continuous over its whole operating lifetime, and owing to excellent insulation property of XLPE-material, firmly longitudinally spliced with inner and external screen of semi-conductive material (extruded in one process), the cable has a high running dependability.
4 core 50 mm² steel tape armoured cable’s design features have mechanical protection, which discusses its typical use for exterior applications. The armour reduces any danger of pinching or damaging the cable, while the steel protects the armoured cable. SWA cables are heavy, which makes them remarkably challenging to bend; therefore they are most matched to underground cabling or fixed to outdoor walls using cable cleats.
Use Cable Cleats to attach the STA cable to walls and structures. Cable cleats give a safe, secure match. Cleats may also be a choice for running cable along the sides of the building, rooftops or outbuildings. Cleats provide safety and security for surface mounting.You must utilize Warning Tape for underground cable positioning. Utilize warning tape offers cables to be visible in case someone was to dig in the area. Always treat safety as critical when you lay cables. Precaution tape reduces the high risk of accidental severing.
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.
