4 core 35 mm² SWA armoured cable, also referred to as SWA 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.d Cables are manufactured with several different layers and elements. The main components of 4 core 35 mm² SWA armoured cable is the:
(1)Conductor. The conductor is usually several cores of plain stranded copper.
(2)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.
(3)Bedding. The PVC bedding serves as a buffer between the inner live component of the cable and the outer components.
(4)Steel Wire Armour. The Steel Wire Armour itself is placed over the bedding, providing the cable protection from stress. Sometimes, the armour can be used as the earth cable.
(5)Cable sheathing. The cable sheath is used to protect the inner components of the cable and supplies more protection from mechanical harm and stress.
Huadong Cable provide a comprehensive series of BASEC-approved armoured cables, manufactured in accordance with a number of British, European and International standards including BS5467, BS6622, BS6724, BS7835, BS EN 50267, IEC 60502 and BS EN 60332-1-2 (for single core cables). Huadong Cables’ range of armoured cable is offered with a Copper (Cu) or Aluminium (Al) conductor and with a Polyvinyl Chloride (PVC) or Low Smoke Zero Halogen (LSZH) sheathing, LSZH sheathings are recommended for use in high density enclosed areas, and are obligatory in some social places.
Due to the 4 core 35 mm² SWA armoured cable’s structure,there are many advantages in use:
4 core 35 mm² SWA armoured cables are distinct in regards to security and protection. As a result of their strong construction, these cables can survive harsh conditions that often associate with heavy-duty applications. The metal armour provides a formidable barricade against intense mechanical stress, such as effect and crushing forces. Moreover, the armour helps shield the insulation from chemical degradation and temperature extremes, ensuring the honesty of the electrical conductors.
Furthermore, the armour offers a measure of grounding safety. If the cable is damaged and a hot wire touches the armour, the grounded armour will trigger a breaker to interrupt the circuit, thereby providing an additional layer of safety.

4 core 35 mm² SWA armoured cable has an additional layer of protection that stops it from being reduced or torn. The armor of the coaxial cable is an aluminum foil wrap that is ribbed like corrugated metal to supply versatility, and around the inside and outside of the wrap is a waterproof compound to stop wetness from penetrating the cable and creating harm.
The interior structure of the 4-core armored cable includes several layers to avoid damage to the cable. The outer sheath protects against rodents, abrasion and twisting and is usually made of plastic. Armoring materials are mainly derived from Kevlar, steel and aluminum foil, and are designed to protect the armored cable from being stretched during installation.
Due to above 4 core 35 mm² SWA armoured cable Feature,which has many applications,as follow:
When transferring data or conducting power in severe environments, safeguarding your cables is essential to safe and dependable operation. This is where 4 core 35 mm² SWA armoured cable come into play. They are used primarily in industrial applications, often in cable trays and raceways. They often not used in bending applications.SWA Cables appropriates for high drop areas and can endure mechanical external forces and significant tension.
These cables are used for electricity provide in low voltage installation system, They are suitable for setup in indoors and outdoors, in cable ducts, under ground, in power and shifting stations, local energy distributions, industrial plants, where there is no danger of mechanical damage.
When laying an 4 core 35 mm² SWA armoured cable underground, the armoured electrical cable must be set out at an enough depth to prevent any prospective harm or disruption. It is better to consider enhancing the depth of direct burial underground or provide additional defense for the armoured cable to ensure security.It is a fact that BS standards do not state a single minimum depth, which is why it is necessary to ensure that the armoured electric cable will not be influenced by common activity.A minimum installation depth that’s followed by all experts is 450mm underground. This depth increases to 600mm for armoured cables in locations where there is a higher possibility for any potential disturbance.
If the 4 core armoured electrical cable is installed directly into the ground, the cable should be bordered by sharp sand to ensure it is protected against any damage to the sheath or insulation. Another precaution that can be taken is the use of electrical warning tape– this can be placed above the sand to suggest that there is an armoured electrical cable present below.In the case of an armoured cable being installed within a pipeline, it is essential to ensure that it is completely watertight to prevent access of any kind.
The armoured mains cable should also be earthed despite whether the armouring is being used as a protective conductor or not. What this does is make certain that the automation disconnection of supply (ADS) requirements are adhered to.Overlooking this may cause problems in the long run because an armoured cable that is not correctly earthed can become a dangerous security danger to users.
