Special purpose MI cable
This series of products take advantage of the high temperature resistance, radiation resistance, corrosion resistance, and high mechanical strength of the all-inorganic material structure of the mineral insulated cable. Through the reasonable selection of structural materials, the maximum operating temperature can reach 1000 ℃. Long-term operation in harsh environments where conventional organic insulated cables cannot be used, such as high temperature, high pressure, and strong corrosion, and in the active area of nuclear reactors.
According to its application areas, product types include:
The high-temperature lead-out cable for automotive sensors has a maximum continuous operating temperature of 900℃ and a short-term operating temperature of 950℃. It is used to transmit various signals detected by the automotive internal combustion engine high-temperature exhaust gas sensor from the internal high-temperature area to the external area;
The mineral insulated cable of the core instrument system can withstand the highest temperature up to 900℃, and it can still maintain good electrical performance when the cumulative γ radiation dose reaches 2x106Gy, and can be used in nuclear power plants Transmission of various detection and control signals in the core instrument system, ignition of hydrogen accumulation on the top of the shell, and detection of neutron quantity;
Forced cooling type hollow conductor mineral insulated cable, the maximum operating temperature can reach 1000 ℃, coolant (such as inert gas, pure water, liquid nitrogen, etc.) can be passed into the conductor for forced cooling, so that the current carrying capacity of the cable can be increased Several orders of magnitude;
Other high-temperature, high-pressure, and strong-corrosion applications use mineral insulated cables, such as signal and power transmission cables for special applications where metallurgy, kiln, chemical and other conventional cables cannot meet the requirements of use.
