Control cable OLFLEX HEAT 125 SC 1x1.5 black BK, single-core 750V /100m/ 1235001

Safety in Demanding Thermal Conditions

This single-core control cable has been designed for applications where standard wiring fails to meet safety or durability requirements. Thanks to the use of cross-linked polyolefin copolymer (XLPO) insulation, the cable maintains flexibility and structural integrity in temperatures ranging from -55°C to +125°C. This operating range makes it an ideal choice not only for industrial installations exposed to significant thermal fluctuations but also for marine environments where atmospheric conditions are particularly severe.

High fire and smoke resistance is a key feature of this model. The cable complies with rigorous CPR standards, achieving fire reaction class Dca, which indicates limited flame spread. Equally important, in the event of a fire, it generates very low smoke density (class s1) and does not emit toxic acids (acidity class a1). This minimizes the risk of suffocation for evacuating personnel and reduces corrosive damage to valuable electronic equipment or production machinery.

Construction and Installation Properties

The core of the cable is a tinned copper conductor, stranded into multiple fine wires (flexibility class 5). This design ensures high flexibility, facilitating installation in tight spaces within control cabinets or around moving machine components. The tinning of the conductor surface further enhances corrosion resistance, which is crucial in environments with elevated humidity or salt presence (e.g., on ships).

The cable features a compact design while maintaining robust insulation: the conductor cross-section is 1.5 mm², making it optimal for control circuits with moderate current. The rated voltage of 450/750 V guarantees safe operation in standard industrial networks, while the small outer diameter of approximately 3 mm allows for easy installation in conduits and junction boxes with limited cross-sections. The insulation is black (BK), which is universal and facilitates identification in complex multi-conductor installations.

Applications and Compliance with Standards

Due to its properties, this model finds wide application in the marine sector and in public facilities with high population density (airport halls, metro stations, shopping centers). Its primary function is to ensure reliable control connections even in emergency situations when other materials would melt or emit toxic gases.

It is worth noting the specifics of the XLPO insulation material – the polyolefin copolymer not only withstands high temperatures but also does not release acids during combustion, thereby protecting nearby equipment from corrosion. The fire classification Dca, combined with low smoke emission s1 and no acid emission a1, makes this cable safe even in areas with high human traffic. The extreme temperature range from -55°C to +125°C allows installation in locations exposed to severe frost or heat without loss of flexibility. The tinned copper conductor with flexibility class 5 ensures corrosion resistance and easy bending during installation work. Designed for control and signal circuits, it is an optimal choice for challenging environmental conditions.

It is important to remember that despite its thin construction (3 mm diameter), this cable offers full insulation protection at voltages up to 750 V. This is a technical solution that combines compactness with high fire safety requirements, eliminating the need for additional thermal shielding in many cases.
