Introduction to Defence Standard Cable | 國防標準電纜簡介
Defence Standard cables, commonly referred to as Def Stan 61-12 cables, are high-specification electrical cables originally developed for military applications by the United Kingdom Ministry of Defence (MoD). These cables are engineered to meet the most stringent requirements for equipment wiring in defence-grade applications requiring high-density wiring within instruments and to connect electronic equipment.
The Defence Standard 61-12 series encompasses multiple parts, each designed for specific applications. These flexible multi-core cables are extensively used in aircraft, process control systems, computers, data processors, military vehicles, and military equipment. As high-grade, compact cables, this range has expanded beyond the defence industry into industrial and commercial sectors.

LSZH電纜消防安全優勢說明
LSZH（低煙無鹵素）電纜在火災情況下具有顯著的安全優勢。根據 IEC 60754 標準測試，普通 PVC 電纜燃燒時會釋放約 28% 的氯化氫氣體，而 LSZH 電纜的氯化氫排放量低於 0.5%。當氯化氫與水（包括人體組織中的水分）接觸時，會形成腐蝕性的鹽酸，刺激眼睛、口腔、喉嚨、鼻子和肺部，使疏散更加困難。
LSZH 材料主要由熱塑性聚烯烴組成，僅含有碳和氫元素，燃燒時產生的煙霧極少且無毒氣體。這些材料通過添加無水礦物如氫氧化鎂和氫氧化鋁作為阻燃劑來實現阻燃性能。
Ventajas de Seguridad contra Incendios de Cables LSZH
Los cables LSZH son obligatorios en muchos edificios públicos y cumplen con estrictas normas locales, europeas (EN 50575, CPR) e internacionales (IEC 60332) de seguridad contra incendios. Sus propiedades retardantes de llama, baja emisión de humo y composición libre de halógenos mejoran la seguridad de evacuación mientras protegen los sistemas críticos del edificio.
Los cables LSZH son prácticamente obligatorios en la infraestructura de centros de datos en todo el mundo debido a su tolerancia cero al tiempo de inactividad durante un posible incendio.
