T/GDWCA 0024-2018 Security signal control cable general specification

Scope

Scope: This standard specifies the terms, definitions, and abbreviations, classification and marking, technical requirements, marking, manufacturing length, test methods, inspection rules, packaging, transportation, and storage for security signal control cables. This standard applies to security signal control cables used in intrusion alarm systems, video surveillance systems, access control systems, residential intercom systems, electronic patrol systems, parking lot (garage) safety management systems, and other security systems composed of these systems. Main technical content: I. General requirements: 1. Copper conductors shall comply with the requirements of GB/T 3956. The single wires in the conductors may be tin-plated, and the tin-plated copper wires shall comply with the requirements of GB/T 4910. 2. One of the following materials shall be used as the insulation material of the product: PE, PVC-J, PVC-J90, WDZR-J, TPE, XLPE, or F. 3. The insulation thickness at any point shall not be less than (90%-0.1% of the specified value) mm. 4. For non-twisted cables, the insulation color sequence shall be black, gray, red, yellow, green, white, purple, and orange, etc. II. Special performance requirements: 1. After the single vertical combustion test, the sample shall not be charred beyond a range of 50 mm to 540 mm from the lower edge of the upper clamp. 2. The insulation and sheath shall be made of halogen-free low-smoke flame-retardant polyolefin insulation materials of type WDZR-J and WDZR-H. 3. The low-temperature test is divided into two grades, Grade A with a test temperature of -50℃, and Grade B with a test temperature of -30℃. After the test, the cable shall still comply with the relevant requirements of low-temperature winding, low-temperature tensile, and low-temperature impact tests, etc.
