VDE-Kabel N706066 J-H(St)H 2x2x0.6 Bd grey communication cable halogen-free drum variable star quad content_copy

The J-H(St)H 2x2x0,6 Bd grey is a halogen-free installation cable from manufacturer VDE-Kabel, specifically designed for use in telecommunication and information processing systems. It is used for the transmission of telephone, measurement, and signal signals, as well as in telephone station and PBX installations for telecommunication systems of all classes. The cable is suitable for use in dry and damp operating environments and can be installed on, in, and under plaster. Its static shield ensures reliable limitation of external electromagnetic interference fields, securing signal quality in critical applications. In the event of fire, the halogen-free composition prevents the formation of corrosive gases and minimizes smoke development, thereby avoiding fire-related damage.

Telecommunication cable with static shield and halogen-free insulation provides high safety in buildings with increased fire protection requirements. The cable is designed for use in information and communication systems where reliable signal transmission and low interference are required. Installation takes place indoors, where the cable can be installed either openly or in conjunction with plaster layers.

Functions and equipment in detail include a bare, single-strand copper conductor with a diameter of 0.6 mm. The conductors are insulated with cross-linked polymer HI1 according to VDE 0207 Part 23, with conductor identification according to VDE 0815. The cabling is arranged in star quad structure (4 conductors per star quad), with 5 star quads assembled into a bundle. The bundle is layered with tape to ensure a stable structure. The static shield consists of a plastic-laminated metal foil (metal side inward) and a bare twin wire, providing additional shielding. The outer sheath is made of polyolefin mixture HM2 according to VDE 0207 Part 24, halogen-free and flame-retardant. The sheath color is grey, corresponding to RAL 7001.

Technology explained simply shows that the cable is rated for a nominal voltage of 300 V and has a test voltage of 800 V. The loop resistance is 130 Ohm/km, which is relevant for signal transmission at low frequencies. The current-carrying capacity is 2.5 A, and the operating capacitance is 120 nF/km. The insulation resistance is 100 MOhm x km, indicating high insulation quality. The capacitive coupling K1 is 300 pF (at 100 m length and 800 Hz), while K9-12 is 100 pF. The cable attenuation is approximately 1.7 dB/km (at 800 Hz). The temperature range is from -5 °C to +50 °C, with a maximum operating temperature of +70 °C. The bending radius is 7.5 times the cable diameter, while for single bending without tension, a radius of 2.5 times is sufficient. The burning behavior corresponds to VDE 0472 Part 804, test type C (equivalent to IEC 332-1), confirming low flame spread and flame-retardant properties.

Compatibility and accessories refers to use in existing telecommunication and information systems, particularly in buildings with increased fire protection requirements. The cable is suitable for use in telephone station and PBX installations and can be used in conjunction with other components of the same product family. Compatibility information refers exclusively to the technical specifications of the cable itself.

Installation and mounting takes place indoors, where the cable may be installed on, in, and under plaster. Installation does not require special tools, as the cable is flexible and easy to handle. The bending strength allows installation without additional tools, provided the specified bending radii are observed to ensure functionality.

Operational advantages lie in the high safety provided by halogen-free materials, which do not release toxic gases in the event of fire. The flame-retardant properties and low smoke emission increase safety within the building. The static shield ensures reliable signal transmission, even in environments with electromagnetic interference. The cable is suitable for use in information and communication systems where high reliability and low interference are required.
