Gloster is guided by the maxim “Safety is not expensive. It is priceless”. We therefore manufacture the safest Fire Survival cables in the Indian market
Gloster Cables Ltd Manufacture Cables that maintain circuit integrity under fire conditions for a certain limited time. These cables are also popularly known as FS cables (Fire Survival Cable) or FR Cable (Fire Resistant Cables), if the fire persists for sufficient duration, as all the plastic components such as insulation, sheathing would all get charred, but however the circuit integrity of the cable will remain for a limited period of time.
FS cables are meant to ensure that the cables used in emergency loads such as emergency lighting [sign boards], emergency ventilation, Pressurization fans, etc. keep working during a fire situation in a building, so that the occupants who are trapped in the building are able to
Fire resistant safety circuits, Public address and emergency voice communication systems, Control and instrumentation systems and High-temperature installation conditions, buildings such as
These cables are able to maintain their circuit integrity even under fire for a defined time as per standards, because of a fire barrier placed over each conductor, preventing the conductors touching each other and getting shorted even in the event of complete insulation burning. The fire barrier usually consists of mica tape[s], which handle high temperatures.
Gloster uses only muscovite MICA tape which can handle up to 1000ᴼC without any problems. These are costlier than phlogopite MICA tape which is a lot cheaper, but has a limited flame temperature handling of up to 800ᴼC only. In addition, for armoured cables Gloster uses an additional fire barrier below the armour for additional safety to protect against the heat generated from the metal particle i.e. armour Cable construction usually as follow:
Conductor: Bare or Tinned copper solid, stranded or flexible type
Fire Barrier : Layers of Glass Mica Tape
Insulation : Heat Resistant PVC, XLPE with additional taping or screening if required
Inner sheath : Fire resistant PVC, FRLS PVC, Low smoke zero halogen
Armour : Galvanized steel wire or strip
Outer sheath : Fire resistant PVC, Flame Retardant Low smoke PVC, LHLS or ZHLS compound
Special construction is also offered application dependent or on requirement.
Some of the fire testing standards like category C of BS 6387 specify testing at 950 ᴼC up to 3 hours. Test method are usually followed as per Standard BS 6387, BS 8491, BS 8434-2, BS EN 50200 and IEC 60331.
Instrumentation cables are multiple conductor cables that convey low energy electrical signals used for monitoring or controlling electrical power systems and their associated processes. The functions of measurement and control are vital in manufacturing and processing applications.
Multicore unscreened / pair / overall screened cables are also manufactured as per BS:5308-I & II: PAS/ BS EN -50288/7 and also as per customer's requirements
Polyethylene / PVC insulated instrumentation cables are offered as per BS:5308-I/ & 2 : 2009: PAS as per customer's requirements or as per various National / International standards such as IEC, BS, VDE, IS, etc. can be supplied by us.
Conductor material shall be annealed bare copper or annealed tinned copper as required.
Insulation / sheathing material used is PVC, HR-PVC and Polyethylene as per customer's requirement.
Shielding material shall be as per customer's requirement. Some types of shielding materials used are given below:
a)Aluminium Mylar tape screening along with drain wire of ATC.
b) Copper tape screening accompanied by drain wire of ATC.
c) ABC / ATC wire braiding
Laid up cores shall be unarmoured or armoured with galvanized round steel wire or strip as per customer’s requirement.
Depending on application and environment, Cables can also be supplied with Flame retardant(FR) or Flame Retardant Low Smoke(FRLS) or Low Smoke Zero Halogen(LSZH) sheathing compounds as per customer’s requirement.
Solar photovoltaic cables are used for transmitting electrical power generated from the solar panel to the charging units, battery banks, change over systems, inverters etc. The cables that are used to carry power from the solar panels to the charging units have to function effectively while remaining exposed to a wide range of severe environmental conditions.
Solar Cables are designed to meet the growing needs of the solar industry. Our solar cables is just the beginning of our plans to develop and launch green technology in wires & cables. Solar Cables are flexible and are resistant to abrasion & moisture. Regardless of your panel- to-grid needs, we have the cables to meet your requirements.
As per EN 50618:2014.

While introducing this product, aspect of SAFETY has been our prime consideration. Thus, Gloster has been the first Company in India having introduced TRIPLE EXTRUSION
TECHNOLOGY with FRLSH properties (HR-FRLSH + FRLSH + FRLSH) with additional features as below. Our theme “Safety is not expensive – It is priceless”.
Conductor higher than 99.97% pure bright electrolyticdomestic-wiregrade copper with Class 5 for better flexibility and laid in unilay profile.
Specially formulated in-house HR-FRLSH insulation in 1 st layer – withstand more rise of conductor temperature while on load. As against 70ᴼC rise of temperature of conventional insulation, ours withstand beyond 70ᴼC continuous and 105ᴼC peak due to HR-FRLSH compound.
Specially formulated in-house thick FRLSH insulation in 2 nd layer – restricts spread of flames, creation of poisonous smoke, toxic & corrosive gases – eliminate panic, asphyxiation, life threat and destruction of expensive electronic goods and house hold properties.
Specially formulated in-house thick FRLSH insulation in 2 nd layer – restricts spread of flames, creation of poisonous smoke, toxic & corrosive gases – eliminate panic, asphyxiation, life threat and destruction of expensive electronic goods and house hold properties.
State-of-the-art Triple extrusion technology – ensures excellent bonding between all three layers.
