Installation cable YDY 750V 4x1.5 without blue conductor YDY-4X1,5

Universal installation cable for diverse applications

The YDY 4x1.5 cable is a reliable choice for electrical installations in both residential and industrial settings. Its design and specifications make it a versatile component suitable for a wide range of projects. This cable is intended for fixed installation indoors, in environments with temperatures ranging from -40°C to +70°C and relative humidity up to 100%.

Construction and properties

The YDY cable features single-strand copper conductors, ensuring good flexibility and ease of installation. The conductor insulation and outer sheath are both made of polyvinyl chloride (PVC)—a standard solution providing basic mechanical and chemical protection. The conductors are twisted, further enhancing resistance to damage during installation. The cable’s rated voltage is 750 V (450/750 V), with a conductor cross-section of 1.5 mm², making it suitable for powering devices with moderate power consumption. Note that the cable does not include a protective (earthing) conductor—this must be considered during installation design.

Applications and benefits

The YDY 4x1.5 cable is ideal for electrical installations in dry indoor environments, concealed under plaster or within protective conduits. It performs well when supplying lighting, power sockets, and other low-power electrical devices. Its round shape facilitates routing in confined spaces. Thanks to its copper conductors, the cable ensures excellent electrical conductivity and minimizes energy losses. The fire reaction class Eca indicates limited flammability—during a fire, the cable will not contribute to rapid flame spread.

Additionally, its versatility is worth noting: this cable type is widely used by electricians due to its ease of handling and broad availability.
