The suspension cable A07VV-F 3x0.75 mm² in transparent version is an electrical cable product for use in lighting installations, particularly for connecting luminaires and lampholders. Marketed independently of the manufacturer under the type designation LEITUNG A07VV-F 3x0.75 TRAN, it serves as a flexible connection solution for indoor applications where an optically inconspicuous and electrically reliable cable is required. The transparent version enables discreet integration into lighting constructions without impairing aesthetic design.

Applications

The cable is intended for use in electrical installations indoors, particularly in lighting systems where a flexible and easily installable connection between lampholder and luminaire is needed. Due to the temperature range of -20 to +80 °C, it is suitable for environments with short-term temperature fluctuations, but not for continuous exposure to extreme temperatures. The voltage limitation to 600 volts restricts its use to low-voltage installations, as commonly found in residential and building electrical systems.

Functions and Equipment in Detail

The cable features three individual conductors, each with a cross-section of 0.75 mm², designed for safe power transmission under low loads. The transparent insulation made of PVC (polyvinyl chloride) ensures good mechanical stability and electrical insulation. The outer diameter is approximately 5.8 mm, enabling compact installation. The cable is not intended for outdoor use, as no specific protection rating (e.g. IP67) is specified.

Technology Explained Simply

The conductor resistance of 28 Ohms per kilometer is typical for copper conductors with a cross-section of 0.75 mm² and affects voltage drops during power transmission. An insulation resistance of over 500 million Ohms per kilometer ensures high electrical insulation and minimizes the risk of short circuits. The nominal capacitance of 65 nF per kilometer is insignificant for signal transmission in low-voltage installations, as data transmission is not intended. The test voltage of 3 kV DC serves as a quality criterion for insulation and confirms the electrical strength of the cable.

Compatibility and Accessories

The cable is compatible with standard lampholders and luminaires requiring a 0.75 mm² connection. It can be connected using suitable plug connectors, terminals, or screw terminals, provided these are rated for the cross-section.

Installation and Mounting

Installation is performed by simply inserting or connecting the cable to the respective connection points. Due to its flexibility and small diameter, routing in confined spaces or through small openings is possible. The cable is not intended for use in damp or wet environments, as no water tightness or protection rating is specified. A proper connection using suitable connection elements is required to ensure a safe electrical connection.

Operational Advantages

The transparent version allows for inconspicuous integration into lighting installations, preserving the aesthetic design of the lighting. The low profile and flexible construction facilitate installation, especially in confined or hard-to-reach areas. Electrical properties such as high insulation resistance and low conductor resistance ensure reliable power transmission under low loads.
