The product is applicable to lead wire in nuclear power equipment
assembly of control rod drive mechanism coil and Stick-bit detector
with temperature index of 260℃and 350℃, and can meet requirements
of high temperature and radiation in nuclear power equipment or
other special conditions. StandardsQ/SC-HD-001-2008 Main properties:
Operating temperature－25℃～+260℃（350℃）
Relative humidity8550℃） Performance of Irradiationintegral neutron flux1×1014 n/cm2
-ray absorbed dose1×107Gy Mold-resistant, seawater-resistant, resistant to alcohol, acetone,
toluene and other organic solvents Type, name and size Type | name | size | EZW260 | High temperature resistant and radiation resistant lead wire, temperature index 260℃ | 0.12~20.0mm2 | EZW350 | High temperature resistant and radiation resistant lead wire, temperature index 350℃ | 0.12~20.0mm2 |
Main technical parameter:
1、The insulation resistance is not less than 500M m after 2 hours
at 220.And the insulation resistance is not less than 100M m after
24 hours at 55and relative humidity of 100%
2、No breakdown in withstanding voltage test (50Hz, 3000V*1min) at
room temperature.
No breakdown in withstanding voltage test (50Hz, 1500V*1min) after
2 hours at 220 ℃. No breakdown withstanding voltage test (50Hz,
1500V*1min) after 1h in water.
3、No breakdown in withstanding voltage test (50Hz, 1500V*1min)
after undergoing radiation of -ray with absorbed dose 1×107Gy.
4、Performance of 350℃ lead wire:
1）Comparison of high temperature test: compare with the silicone
rubber cable, fluorine plastic line, PEEK line, polyimide line at
450 ℃.
2）Thermodynamic life simulation test: extrapolation temperature is
410 ℃
2）Good low-temperature resistant performance
The 260℃high temperature resistant and radiation resistant lead
wire has been used in C1 project of Chashma nuclear power plant in
Pakistan. Pakistan C1 project is always safe since putting into
operation in 1998. |
