BS EN 50525 300/500V PVC Flexible CY Control Cable Copper Braid Screened
DOWNLOAD CATEGORY SPECIFICATIONS
Quick details
CY Control Cable is Plain Annealed Flexible Copper Conductors / PVC Insulated / Tinned Copper Wire Braid (TCWB) / PVC Sheathed. 300/500V
Application
Copper braided multicore PVC CY cable for protection against electrical interference. Suitable where a high degree of circuit integrity is required and where interference can prevent accurate signal transmission in low or medium voltage installations.
The cable is designed to be used as an interconnecting cable for measuring, controlling or regulation in control equipment for assembly and production lines, conveyors and for computer units.
The shielding on CY cable helps to reduce electromagnetic interference; therefore CY cable is commonly used in situations where reduced interference signal and data transmission is required.
If protected correctly electricians have found that CY can be useful in outdoor projects - however it is recommended and most commonly used for indoor projects in dry or moist conditions.
