The VDE-Kabel JE-H(ST)H 4X2X0,8 E30 OR is a halogen-free telecommunication cable specifically designed for use in control and regulation systems as well as fire alarm systems. This cable ensures the functional integrity of the system for a period of 30 minutes under fire exposure, making it suitable for applications with high safety requirements. It is installed in dry and damp operational environments, particularly in and under plaster, and is not intended for high-voltage installations or underground laying. The cable features an orange outer sheath, with the fire alarm cable version available in red.

Applications

The cable is intended for signal and measurement value transmission in safety-critical systems, particularly in fire alarm systems, where functionality must be maintained even under fire conditions. The DIN 4102-12 standard for functional integrity E 30 ensures that the cable retains its electrical properties for 30 minutes even at elevated temperatures. Installation takes place indoors, and the cable can be used in both dry and damp environments.

Functions and Equipment in Detail

The cable consists of four pairs, each pair comprising two single-strand, tinned copper conductors with a diameter of 0.8 mm. The conductor insulation is made of a cross-linked, halogen-free, ceramifiable polymer blend, which forms a ceramic layer when exposed to heat, thereby maintaining electrical insulation. Conductor identification follows VDE 0815, with standardized color coding for the pairs: Pair 1 blue-red, Pair 2 gray-yellow, Pair 3 green-brown, Pair 4 white-black. Each bundle is marked with a numbered plastic identifier to facilitate identification.

Technology Explained Simply

The cabling structure consists of 2 conductors per pair, 4 pairs per bundle, with bundles twisted in layers. A stranding tape provides additional stability. Shielding consists of a polyester-laminated aluminum tape, supplemented by a twin wire with a 0.8 mm diameter, ensuring effective electromagnetic shielding. The outer sheath is made of halogen-free polymer blend and is orange, making the cable visually identifiable. The rated voltage is 225 V, and the cable withstands installation temperatures from -5 °C to +50 °C and post-installation temperatures from -30 °C to +70 °C. The bending radius is 7.5 times the cable diameter, enabling flexible installation.

Compatibility and Accessories

The cable is designed for use in fire alarm and control systems, with compatibility ensured for corresponding devices and systems. The halogen-free composition and ceramifiable insulation ensure low smoke emission and prevent the release of corrosive gases during fire exposure. Testing is carried out according to EN 50266-2-4, IEC 60332-1, IEC 60332-3 Cat.C for flame retardancy, and VDE 0472 T. 814-IEC 60331 for insulation integrity FE 180. Functional integrity E 30 is verified according to DIN 4102-12.

Installation and Mounting

Installation takes place indoors, with the cable suitable for laying in and under plaster. Maximum installation and operating temperatures are defined, with the cable capable of withstanding temperatures up to +70 °C after installation. The bending radius of 7.5 times the cable diameter allows flexible installation without damaging the cable. The cable is not intended for underground laying or high-voltage applications.

Operational Advantages

The cable provides high safety due to its halogen-free composition, which does not release toxic gases during fires. The ceramifiable insulation ensures insulation integrity FE 180, meaning electrical insulation is maintained even at high temperatures. Functional integrity E 30 guarantees that the cable maintains its function for 30 minutes under fire conditions. Shielding protects against electromagnetic interference, enhancing signal quality in control and regulation systems. Color and identification according to VDE 0815 facilitate identification and maintenance of cables within the system.
