PAS BS 5308 Part 1 Type 2 PE/OS/PE/SWA/PVC Cable
APPLICATION
Publicly Available Standard (PAS) BS 5308 cables are designed
to carry communication and control signals in a variety of
installation types including those found in the petrochemical
industry. The signals can be analogue, data or voice type and
from a variety of transducers such as pressure, proximity or
microphone. Part 1 Type 2 cables are designed where a greater
degree of mechanical protection is required namely outdoor /
exposed or direct burial at suitable depth

I. Overview
BS 5308 Part 1 Type 2 PE/OS/PE/SWA/PVC Cable is a cable product widely used in industrial, commercial, and construction fields. The name of this cable reflects its specific structure and material composition, and each layer of the structure endows the cable with unique performance and functions.
II. Structural Composition
(I) Polyethylene (PE) Insulation Layer
Electrical Insulation Performance
Polyethylene is an excellent electrical insulating material. In this cable, the PE insulation layer can effectively prevent current leakage and ensure efficient power transmission. It has a high resistivity and can withstand relatively high voltages without breakdown, thus ensuring the safety and stability of the cable under normal working voltages.
Physical Properties
The PE insulation layer has good flexibility, which enables the cable to be bent to a certain extent during installation without damaging the insulation performance. It also has good abrasion resistance and can resist mechanical friction that may be encountered during laying and use.
(II) Steel Wire Armour (SWA)
Mechanical Protection Function
The steel wire armour provides strong mechanical protection for the cable. It can prevent the cable from being damaged by external forces such as extrusion and impact. In the case of underground laying, being easily squeezed by heavy objects in an industrial environment, or being likely to be collided with other devices in a cable trench, the SWA can effectively protect the conductors and insulation layers inside the cable and ensure the normal operation of the cable.
Anti - interference Ability
The steel wire armour also has a certain electromagnetic shielding effect. In some environments with electromagnetic interference, such as areas close to large motors, transformers, etc., the SWA can reduce the interference of the external electromagnetic field on the signal transmission inside the cable and also prevent the internal signals of the cable from radiating outward to interfere with other devices.
(III) Polyvinyl Chloride (PVC) Outer Sheath
Environmental Protection Function
The PVC outer sheath provides outer - layer protection for the cable. It can resist the erosion of external chemical substances, water ingress, and ultraviolet radiation. When used outdoors, the PVC outer sheath can prevent natural factors such as rain and sunlight from damaging the internal structure of the cable and prolong the service life of the cable.
Identification and Recognition
The color of the PVC outer sheath can be customized according to different application requirements, which is convenient for marking and identifying the cable during installation and maintenance. For example, in a complex cable wiring system, cables of different colors can represent different circuits or functions, which helps to improve the efficiency of installation and maintenance.
IV. Application Fields
Industrial Field
In industrial environments such as factories, mines, metallurgy, and chemical industries, BS 5308 Part 1 Type 2 PE/OS/PE/SWA/PVC Cable is used to supply power to various electrical devices, such as motors, power distribution cabinets, and lighting equipment. Its good mechanical performance and environmental adaptability can meet the complex working condition requirements in the industrial environment.
Commercial Field
In commercial buildings such as shopping malls, office buildings, and hotels, this cable is used in the power distribution system. Its beautiful outer sheath (with customizable colors), stable electrical performance, and reliable mechanical protection can meet the requirements of safety, reliability, and aesthetics of power supply in commercial buildings.
Construction Field
In electrical installation projects of residences and public buildings, this cable can be used for indoor and outdoor power transmission. For example, when laid in the shafts of buildings or in outdoor cable trenches, it can adapt to various conditions during building construction and use.
