Oil/Gas Industrial Cable
PAS BS 5308 Part 1 Type 2 Mica/XLPE/IS/LSZH/SWA/LSZH (Fire Resistant) 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 of analogue, data or voice types 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 or where there is direct burial at a suitable
depth. Suitable for fire resistant installations.

Introduction to BS 5308 Part 1 Type 2 Mica/XLPE/IS/LSZH/SWA/LSZH (Fire Resistant) Cable
I. Overview
BS 5308 Part 1 Type 2 Mica/XLPE/IS/LSZH/SWA/LSZH (Fire Resistant) Cable is designed for special needs. It excels in fire - resistance, electrical, mechanical, and environmental aspects, and is used in high - safety - demand places like buildings, industrial facilities, and transportation hubs.
II. Structural Composition
(I) Mica
Fire - resistance Core
Mica is crucial for the cable's fire - resistance. It can withstand high temperatures and prevent flame from spreading into the cable, protecting its structure and circuit integrity during a fire.
Insulation Aid
Besides, mica, along with XLPE, enhances insulation in complex electrical environments like high - temperature and humidity, reducing fault risks.
(II) XLPE Insulation Layer
Efficient Insulation
XLPE has high insulation resistance and low dielectric constant, reducing power loss during transmission, preventing current leakage, and ensuring equipment operation.
Mechanical Support
With good mechanical properties like high tensile strength and tear - resistance, XLPE allows the cable to endure external forces during installation and use without easily damaging the insulation.
(III) Inner Separation Layer (IS)
Layer Separation
The inner separation layer separates XLPE from other layers, preventing chemical reactions or physical wear, protecting XLPE's integrity and insulation stability.
Structural Stability
When the cable faces mechanical forces like vibration and impact, this layer buffers, reducing internal displacement and deformation, maintaining overall stability.
(IV) LSZH Sheath Layer
Fire - resistant and Green
The LSZH sheath shows fire - resistance and environmental - friendliness. In a fire, it emits less smoke and toxic gases than halogen - containing materials, aiding evacuation and rescue and being eco - friendly.
Mechanical Protection
It also provides some mechanical protection against common damages in normal conditions, safeguarding the cable's internal structure.
(V) Steel Wire Armour (SWA)
Mechanical Protection
SWA strongly protects the cable from mechanical damage in complex environments like underground laying or industrial collisions.
Electromagnetic Shielding
It shields against electromagnetic interference, improving signal transmission quality and stability in interference - prone areas.
III. Performance Characteristics
(I) Fire - resistance Performance
Good Fire - resistance
The cable has excellent fire - resistance. Mica and LSZH sheath keep the circuit intact in a fire, ensuring key equipment operation like fire - fighting and emergency lighting systems.
Flame Spread Control
Its structure and materials can control flame spread, reducing the fire's spread range and enhancing building safety.
(II) Electrical Performance
Efficient Power Transmission
XLPE's low - dielectric - loss enables efficient power transmission, reducing loss in long - distance transmission, improving energy - use efficiency, and cutting costs.
High - insulation Reliability
Mica and XLPE form a reliable insulation system. In complex electrical environments, the cable maintains stable insulation, preventing breakdowns.
(III) Environmental Adaptability
Low - Smoke Zero - Halogen Advantage
The cable's low - smoke zero - halogen feature is great for environmental protection. In crowded places, it doesn't release toxic smoke in a fire, protecting lives and the environment.
Wide - range Tolerance
It can adapt to various environmental conditions. Different layers work together to ensure electrical and mechanical properties aren't severely affected.
(IV) Mechanical Performance
High Strength and Toughness
SWA and XLPE give the cable strength and toughness. During laying, whether overhead or underground, it can withstand external forces without breaking or getting damaged.
Good Bending Performance
Despite its strength, the cable can be bent moderately to meet installation path requirements without seriously affecting internal layer performance.
IV. Application Fields
Construction Field
In buildings like high - rise, commercial, hospitals, and schools, the cable is used in fire - protection, emergency lighting, and elevator control systems. Its properties ensure safety and equipment operation in a fire.
Industrial Field
In petrochemical, metallurgical, and power industries, it transmits power and signals. It adapts well to complex industrial conditions like high - temperature, humidity, chemicals, and collisions.
Transportation Field
In transportation hubs like subways, stations, and airports, it's used in lighting, signal - transmission, and power - supply systems. Its fire - resistance and low - smoke zero - halogen features improve fire - safety, and its reliability ensures facility operation.
