Some Features Of Fire Resistant Cables In the event of a fire, it may be burned out and cannot be operated, but it can prevent the spread of the fire. Typically a halogen free cable is made of polypropylene, which does not produce a dangerous gas or acid in fire conditions. VKG: The fire properties for cables are of great importance. AB: To answer this question, the effect of fire on cables needs to be explained. In addition to being toxic, hydrogen chloride is corrosive to equipment. Insulators and structural components made from FR4 with the UL standard marking are guaranteed to prevent fire propagation and extinguish the fire quickly. PK: Fire retarding properties in cable are of great importance. However, the price is high. So in a high risk populated area where escape is limited LSHF cables are strongly recommended. f. Constantly upgrade the raw materials and processes to ensure better products at optimum costs. Ongoing research has produced a world class range of high quality cables such as Saffire, Firetuf and Railsure that meet or surpass British Standards. The aluminum alloy conductor is added relevant trace elements in the aluminum conductor, so that its resistivity is lower than the pure aluminum conductor, which solves the disadvantages of poor mechanical properties, easy breakage and easy creep of pure aluminum . In case of fire in plant or at any other place, the burning elements should not produce black and suffocating smoke which results in to zero visibility and difficulty in breathing. Generally, for outdoor application where the cables are buried, Low Smoke Zero Halogen properties are not needed as the oxygen level is low and does not support burning. Hydrochloric acid can have devastating effects on adjacent equipment. Approved by BASEC, LPCB & LUL (section 13) Prysmian FP200 Gold is undoubtedly the best quality fire alarm & emergency lighting cable available. These standards specifies various requirements for smoke density rating, halogen content, temperature index, oxygen index, Corrosivity of combustion gases, pH index, flammability tests under different conditions, circuit integrity test, light transmission under smoke, etc. (Unsubscribe at any time.).

FR4 has no moisture absorbing properties, so it will not expand or contract when humidity changes and is not affected by direct exposure to water, making it excellent for marine components. The definition of a fire-resistive or fire-rated cable is a cable that will continue to operate in the presence of a fire. Cables, therefore, have to be shock proof as well as short circuit proof. With another ingredient EVA, we are able to make cable compound which will produce almost white smoke and with very-very low halogen content toxic gases. PK: Definitely manufacturers have to comply to all above mentioned tests wherever required, and hence has to have: a. The process is complicated, the construction is difficult in the oil irrigation area, important wooden public buildings, high-temperature places, and other fire-resistant requirements, and the economy can accept the occasion and use fire-resistant cable. Cables intended to fulfil this type of function are often labelled as one of the following: Both LSZH and LSF are used to limit smoke, fumes and halogen given off in fire conditions. Whereas LSHF cables are less flexible and a higher cost but with a significant reduction in toxic gas and smoke. Manufacturers have to select the proper source for such cable compounds and sometimes need to blend these compounds in their in-house facilities to meet the desired requirement. INVESTORS SHOULD NOT SUBSCRIBE FOR ANY SECURITIES REFERRED TO IN THIS DOCUMENT EXCEPT ON THE BASIS OF INFORMATION CONTAINED IN ANY PROSPECTUS. The definition of flame-retardant cable is a cable that will not convey or propagate a flame as defined by the flame-retardant or propagation tests. And the cable is easy to install, so many customers are willing to buy it. These risks and the mode in which the fluid operates at higher pressures can make it easy to justify the use of a fire-resistant fluid. The basic structure of the flame retardant cable is: Flame-retardant wires are characterized by delaying the spread of flame along the cable so that the fire does not expand. At room temperature when the oxygen content in the air exceeds the oxygen index, the material will burn by itself automatically. A plenum is the air return path of a central air handling system. The NEC provides additional requirements. Manufacturers in organized sectors have responded equally and use virgin raw materials meeting different test requirements with zero tolerance. Copyrights 2000-2021: Relemac. We are also offering next generation cables i.e Fire Survival cables which maintain circuit integrity for minimum 3 hrs up to 950 deg Celsius under fire, water and shock conditions to ensure transmission of signals and communication. Cables used in plenums are required to have a more stringent test than that of the horizontal or vertical flame tests. c. Has to have knowledge of formula-tion and engineering of raw materials. However, mere transmission is not enough. When do you need a fire-rated circuit integrity cable? Costs still have precedence over safety. Fire-resistive cables maintain circuit integrity and continue to work for a specific time under defined conditions such as fire. Disadvantages [ edit] The termination points: While the length of the MI cable is very tough, at some point, each run of cabling terminates at a splice or within electrical equipment. where the cables needs to operate under direct fire to supply power to these emergency equipments. The amount of smoke produced when burning fire-resistant cable is less, especially with refractory materials, making fire-resistant flame retardant performance, especially in the case of burning, accompanied by water sprinkling and fire fighting, the cable can still maintain the integrity of the wire operation. Therefore, the fire-resistant cable produces little smoke in the fire, and there is no halogen which is of great help to the environment. keep working. Hydrogen chloride emissions of LSF cable may reach up to 18%. In building construction, electrical cable sheathing is a potential source of fuel in the event of a fire.
