The cable NYY-J 5X35 RM from VDE-Kabel is a fixed installation power and control cable designed for use outdoors, in the ground, in indoor spaces, and in cable ducts. It features a copper conductor, bare and manufactured according to VDE 0295, where the designation RM stands for round multi-strand. The cores are insulated with PVC and marked according to VDE 0293-308, with the marking J indicating the presence of a green-yellow protective conductor. The outer sheath is also made of PVC in black, ensuring high mechanical and chemical resistance. A filler layer ensures an even cable structure and improves installation flexibility.

Applications include supplying electrical installations in industrial, commercial, and residential buildings, particularly in areas requiring high mechanical load capacity and weather resistance. The cable is suitable for underground installation, installation in cable ducts, and indoor use where permanent and secure power supply is required. Outdoor use is possible due to the protection rating and materials, with ambient temperature during installation ranging between -5 °C and +70 °C.

Functions and equipment in detail include a rated voltage of 0.6/1 kV, enabling use in medium- and low-voltage installations. The test voltage is 4 kV, highlighting the cable’s electrical strength. The maximum operating temperature is +70 °C, with the cable surface operable between -30 °C and +70 °C after installation. The bending radius is 12 times the cable diameter, as it is a multi-strand cable, allowing flexible installation. Flame retardancy corresponds to test method B according to VDE 0472 Part 804 (equivalent to IEC 332-1), ensuring limited flame spread.

Technology explained simply shows that the cable offers high mechanical strength and resistance to external influences. The PVC insulation and PVC outer sheath provide good insulation performance and protection against moisture, mechanical damage, and chemical influences. The use of copper as conductor material ensures high electrical conductivity and longevity. The multi-strand construction (RM) increases flexibility and facilitates installation, especially in tight bends.

Compatibility and accessories include use in standard installations for power and control lines. The cable is suitable for installation in earth channels, cable ducts, and indoor spaces and can be connected with standard cable lugs, terminals, and connectors. It is not specifically designed for optical or data transmission systems, but for the transmission of electrical power and control signals.

Installation and mounting require adherence to specified bending radii and temperature limits. The cable should be installed at temperatures between -5 °C and +70 °C to ensure optimal installation flexibility and material integrity. After installation, ambient temperature can reach -30 °C without impairing cable function. Installation typically occurs from reels, with length varying according to delivery.

Operational advantages include high reliability, longevity, and ease of maintenance. The cable is designed for permanent operating conditions and requires no special maintenance. The flame-retardant design reduces fire risk, and the high mechanical strength protects against damage from external influences. The use of copper as conductor material ensures stable and efficient power transmission.
