800 degrees Celsius fire resistance proof wireThis cable's fire resistance enables it to keep the electricity flowing in the event of a fire. According to EN50200, it can withstand temperatures of up to 800 °C for three hours.
Voltage range: 300/500 V. 90 °C is the maximum core temperature. Radius of minimum bend: 10 times the diameter. The outer heath is orange.
The Principal DifferencThe passage continues.Flame-retardant and fire-resistant cables differ greatly from one another. Flame-retardant cables usually stop a fire from spreading to other areas, while fire-resistive cables keep the circuit intact and function for a predetermined amount of time under predetermined circumstances.
Another of our durable, flame-resistant fluoropolymers is PTFE. It is a highly respected plastic due to its superior thermal and electrical insulation, low coefficient of friction (non-stick qualities), and good chemical resistance.
When coupled with nitrogen, phosphorus, or bromine, a variety of inorganic and mineral compounds are utilized as flame retardants or as components of flame retardant systems. Graphite, silica, nitrogen, and inorganic phosphates like polyphosphate and ammonium phosphate are among the inorganic substances.
Retardant to FlamesFlame Retardant (FR), Flame Retardant Low Smoke & Halogen (FRLSH), and Flame Retardant Low Smoke Zero Halogen (FR-LSOH) are possible materials for the sheath. Some designs, known as "fire resistant" or "fire survival" cables, also need to pass high temperature circuit integrity tests.
The NG-A fire-rated electrical cables' outer sheath is composed of aluminum; hence, the copper tape's longitudinal welding embossing is replaced by an aluminum tape longitudinal welding embossing, and the cable core within may be covered in multiple layers of refractory insulation.
Even hours after a fire starts, these cables are still able to function. In the event of a fire, according to safety regulations, we should turn off the power supply. However, some circuits must continue to function, even only briefly. Two hours after a fire starts, cables with a 2-hour fire rating can continue to operate.
With its enhanced qualities, XLPE wire resists melting and can tolerate temperatures as high as 120°C for lengthy periods of time without losing its chemical and mechanical characteristics. Along with an increase in resistance to abrasion and environmental stress, the juvenile modulus is also raised.
The period in minutes or hours that the assembly or building materials have sustained a typical fire exposure is known as the fire resistance rating, or FRR. How is a material's FRR measured? The amount of time it takes for a particular material or building to fail in a fire is used to compute fire resistance ratings.
