Shenzhen Lilutong Technology Industry Co., Ltd., based in 2001, is primarily engaged within the product design, R & D, production and gross sales of a full vary of wires and cables, akin to fireplace-proof cables, silicon cables, rubber cables, low smoke halogen-free cables, communication cables, floating cables, chilly resistant cables, management cables, versatile cables, elevator cables, robotic cables, new energy dedicated cables, optical fiber integrated traces, and many others The products are broadly used in fireplace combating and safety, communication, new vitality, solar power, high-rise buildings, rail transit, bridges, industrial 4.Zero equipment, ships, aviation, navy business and other fields, and have won the titles of Shenzhen High-Tech Enterprise, National Contract and Credit Enterprise, Shenzhen Love Enterprise, Shenzhen Top 100 Fire Fighting and Security Enterprises, Council Unit of Wire and Cable Association,National First-Class Measurement System Qualified Enterprises, Chinese Outstanding Private Science and Technology Enterprises. The 110-120-volt circuits have two conductors -- one neutral (white) wire and one hot (black) wire. While the standard tells the appliance and some technical details, the category defines these two crucial traits. The cable should maintain its electrical continuity for 30 minutes whereas underneath the water spray.

For a fabric with a recognized oxygen index, 15 ± 2 check specimens are sufficient, whereas for supplies with unknown oxygen index, 15 to 30 take a look at specimens are required. The material combination used within the Habiaflame™ idea doesn’t rely on extruded plastics. In addition, mineral insulated cable has higher performance than flame retardant cables made with copper core, copper sheath, magnesium oxide insulating material processing, known as MI cable (mineral insulated cable). CPR got here into impact with European Parliament and Council Decision 2011/305/EU. The principle function of CPR is to evaluate the efficiency of building products in accordance with standards and provide users and notified bodies with accurate info by labeling. With CPR, Industry professionals, public authorities and customers can evaluate the efficiency of products from completely different manufacturers in different nations. BIS is the national Standards Body of India working underneath the aegis of Ministry of Consumer Affairs, Food & Public Distribution and Government of India. Quality Assurance: Goldmedal is understood for its commitment to quality and adheres to industry standards and regulations in the production of wires and cables. Due to the vastly completely different nationwide check requirements across Europe a direct comparability of cables between requirements is sort of inconceivable - except they're all examined to all the above relevant protocols they don't seem to be interchangeable.

There should be a propane fuel burner 600 mm above the floor of the chamber. 50°C, the place the flame supply is placed 70mm above and 45mm away from the cable. The flame source is held at a 45° angle onto the cable. The cable is mounted on the wall in a Z-shaped configuration with a minimum bending radius and subjected to a flame at a temperature of 950 ± 40°C. The declared voltage of the cable is utilized to the conductors, and every 30 seconds, a drive produced by the free-falling action of a steel bar with a mass of 25 kg is utilized to the wall the place the cable is related, hanging it at a 60° angle. The declared voltage of the cable is applied to the conductors, Fire resistant cable and it is subjected to a flame at a temperature of 950 ± 40°C for 180 minutes. The take a look at determines the electrical continuity is maintained when the cable is subjected to water spray beneath the declared voltage. 40°C. The cable's declared voltage is applied to the conductors, and each 5 minutes, a a force produced by the free-falling motion of a steel bar with a mass of 25 kg is applied to the cable by placing the wall it's connected to at a 60° angle.

40°C. The cable's declared voltage is utilized to the conductors, and every 5 minutes, a drive produced by the free-falling motion of a steel bar with a mass of 25 kg is applied to the cable by striking the wall it's related to at a 60° angle. To describe a cable as ‘LSHF’, it must move two exams: (a) a smoke cube test, which sets a most accumulated smoke density produced when burning the cable with a typical fire, and (b) a corrosive and acid gas check where the cable supplies are roasted and should give off a most of 0.5% acid gas. Goldmedal wires are fire retardant for the reason that wires have self-extinguishable features. Because of this, a smoke density check is conducts to determine the amount of smoke that a cable might emit within the occasion of a fireplace. In the course of the check, measurements are taken for the amount of heat that launched, smoke production, oxygen consumption, and CO2 manufacturing. Alternatively, flame resistant cables are manufactured from inherently non-flammable materials. The Limiting Oxygen Index (LOI) take a look at method is used to determine the minimum oxygen concentration required for the continued combustion of plastic materials underneath standart circumstances.
