BTTRZ wire Introduction
Introduction: BBTRZ is a flexible mineral insulated cable, commonly known as
fire resistant cable. It can withstand 1000 voltage at a flame
temperature of 950 degrees for 3 hours without breakdown.
In addition to the advantages of fire resistance, explosion-proof,
temperature resistance and large current capacity, it also has the
following characteristics: it is not easy to absorb moisture and
has better insulation performance. Stable, multi-core, fixed-length
production, no intermediate joints, flexible structure, easy to
bend, no need for special terminals, no attachments, suitable for
all kinds of laying methods, general electrical personnel can be
carried out according to the conventional cable laying method.
Characters:
Flexibility: Because the conductor of the cable uses mature
stranding technology, and the sheath is made of cross-linked
inorganic material, non-copper tube type. Therefore, it is not only
lightweight but also has soft characteristics. It avoids wiring
terminal problems that are often encountered when designing and
installing rigid mineral insulated cables.
Fire protection: Since the constituent materials of the cable are
all mineral compounds, the non-combustibility of the cable itself
is determined. The product complies with BS and IEC international
standards, can withstand 950 ° C for 3 hours of combustion under
the condition of charging, and guarantee the normal operation of
the circuit. Therefore, it can remain unchanged even above the
short-circuit temperature.
Low smoke: Flue gas divergence test according to IEC1034, the test
transmittance is over 80% (standard 60%).
Halogen-free: Due to the insulation of the cable, the jacket is
made of an inorganic compound material, and there is no usual PVC
material. Therefore, even under fire conditions, no acid gas is
diverged.
Temperature resistance: The cable can work for a long time at an
ambient temperature of 125 ° C. In an emergency, it can also work
shortly below 1080 °C.
Corrosion resistance: The mineral compound material used in the
cable is more resistant to corrosion after irradiation, and can be
applied without any additional measures.
Large current carrying capacity: Compared to cables of the same
cross section, flexible mineral insulated fireproof cables not only
transmit higher currents but also withstand large overloads.
High mechanical strength: Flexible mineral insulated fire-resistant
cable is made by cross-linking specially developed inorganic
compounds through high-energy electron B-rays; it overcomes the
lack of mechanical properties of cables due to the rapid
deterioration of material aging characteristics.
