数据电缆Liyy-liycy系列

绝缘 屏蔽 耐磨损

技术数据灵活控制信号电缆，具有2个独立屏蔽和绝缘核心。优选的应用用于电子系统，控制和调节系统，测量和信号系统以及用于寻呼和对讲系统的互连电缆的可移动连接电缆。特殊功能每根电缆都有两个可单独屏蔽的核心，无需无干扰控制脉冲传输。屏蔽也被绝缘，以防止来自外部接地的干扰。施工数据导线和横截面，细线铜线16×0.20 mm = 0.50mm 2。核心绝缘PVC，彩色，第二种颜色为耐磨彩色环。核心Ø除两个屏蔽芯外，1.80±0.1毫米。编织屏蔽（在1ST =白色和2ND =棕色核心）编织屏蔽锡罐，16 x 4 x 0.10 mm，约。80％的视觉覆盖范围。两个屏蔽中的每一个由PVC软管夹套覆盖，壁厚为0.5mm。 Total Ø of each of the two shielded cores = 3.3 ± 0.1 mm. Twisted structure 2 cores each with a Cu shield and PVC sheath are twisted with 2 to 14 unshielded PVC cores to form a cable. Outer jacket PVC, light grey as per RAL 7032. Jacket wall thickness increasing from 0.8 mm for 4 cores, through 1.0 mm for 8 cores to 1.2 mm for 16 cores. Electrical and thermal properties at 20°C (VDE 0812) Conductor resistance max. 37 Ω/km Insulation resistance > 20 M Ω x km Capacitance approx. 80 pF/m core/core approx. 45 pF/m LiYCY core/core, shield earthed approx. 180 pF/m LiYCY core/core/shield (measured at 1 kHz)
