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 mineral insulated cable's all-inorganic material structure. 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 strong corrosion, and in the active area of nuclear reactors.
According to its application areas, product types include:
The high-temperature lead-out cable of automobile sensors has a maximum continuous operating temperature of 900°C and a short-term operating temperature of 950°C. It is used to transmit various signals detected by the automobile internal combustion engine high-temperature exhaust gas sensor from the internal high-temperature area to the external area;
The core instrument system mineral insulated cable can withstand the highest temperature up to 900°C. It can still maintain good electrical performance when the cumulative γ radiation dose reaches 2x106Gy. It can be used for the transmission of various detection and control signals in the nuclear power plant 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 highest 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 by several orders of magnitude ;
Mineral insulated cables for other high temperature, high pressure, and strong corrosive occasions, such as signal and power transmission cables for special applications where conventional cables such as metallurgy, kilns, and chemicals cannot meet the requirements of use.
