应用工况
M-PAC 4.0 mm radiation-resistant communication 与 distributed sensing (DTS/DAS) optical cable enclosing graded-index radiation-hardened fibres inside a hermetic M-PAC metallic protection tube 与 a 4.0 mm black 外护套 配有 dual yellow stripes.
Hermetic laser-welded metal tube blocks hydrogen ingression, moisture 与 radial crushing in nuclear ducts.
Radiation-hardened doped/pure-silica fibres maintain low RIA (radiation-induced attenuation) up 至 +125 °C.
Compact 4.0 mm outer diameter routes easily through stainless instrumentation conduits 与 reactor penetrations.
Work-hardening metallic protection tube is 适用于 static or low-cycle installation, not high-cycle 拖链.
