Product catalog summary
Specifications:
The document details low-frequency cables, specifically shielded and PE-insulated cables for microphones, recording heads, and dictation devices. The conductors are made of plain copper strands with a cross-section of 0.08 mm², insulated with transparent PE to a diameter of 1.6 mm. The cable structure includes a PE core shielded by twisted plain copper wires with a shield coverage of ≥ 90%, and a silver-grey PVC jacket. The capacitance is approximately 80 pF/m, and the operating voltage is a maximum of 350 V~.
Conductor Resistance:
The resistance varies with the cross-section of the conductor: 0.08 mm² = 236 Ω, 0.11 mm² = 180 Ω, 0.14 mm² = 135 Ω, 0.50 mm² = 40 Ω, and 0.75 mm² = 26 Ω.
Temperature and Voltage:
The cables operate within a temperature range of -20°C to +80°C. The test voltage is approximately 2.5 times the operating voltage. Insulation resistance for PVC-insulated cores is ≥ 20 MΩ X km, and for PE-insulated cores, it is ≥ 1,000 MΩ X km.
Individually Shielded Cables:
These include low-capacitance diode cables and microphone cables for stereo audio applications. The diode cables have conductors insulated with PE to 1.6 mm Ø, shielded by twisted plain Cu wire, with a shield coverage of ≥ 90%. The microphone cables have four individually shielded cores twisted together, with a capacitance of approximately 90 pF/m and an operating voltage of max. 250 V~.
Device Connection Cables:
These cables have conductors insulated with PVC to 1.0 mm Ø, shielded by braided plain copper wires with a shield coverage of ≥ 80%. The capacitance is 100 pF/m, and the operating voltage is max. 250 V~.
Technical Data:
The document provides details on the total diameter, weight, number of cores, and cross-section of one core for various cable types. It also includes pricing information for different quantities, with net prices in EUR per 100 m.
