HEYFLT23 oil filled armored aluminum sheathed railway long-distance symmetrical cable

HEYFLT23 oil filled armored aluminum sheathed railway long-distance symmetrical cable

HEYFLT23 armored aluminum sheathed railway long-distance symmetrical cable

Railway long-distance symmetrical communication cables below 1.0 use PE insulation, while cables above 1.0 use a three-layer insulation structure of skin foam skin from the 1990s. The inner layer adjacent to the conductor is a solid skin with a thickness of 0.01mm, which is used to enhance the bonding strength between the conductor and the insulation layer, and to improve the longitudinal moisture resistance of the conductor surface; The middle layer is a physical foam layer, which has uniform, fine, and distinct foam pores; The outer layer is a solid layer with a thickness of 0.05mm, used to enhance the mechanical strength and moisture resistance of the insulation layer. This insulation structure ensures that the cable has excellent and stable electrical performance, as well as excellent physical and mechanical properties and moisture resistance. The moisture resistance of the oil filled low-frequency symmetrical communication cable is particularly excellent, and it can be maintained without inflation.

Usage characteristics: This product is suitable for long-distance trunk communication lines and interval communication. The 0.9mm high-frequency four wire group is used for 156kHz analog communication systems, the 0.9mm low-frequency four wire group is used for audio communication, the 0.6mm and 0.7mm twisted pair groups are used for audio communication, and the 0.6mm and 0.7mm insulated single wires are used for signal transmission, alarm, remote control. This product has excellent shielding performance and is suitable for installation in electrified sections or other areas with strong electrical interference.

The operating temperature of the cable is -40~60 ℃
Environmental temperature for cable laying: not less than -10 ℃
The allowable bending radius of the cable shall not be less than 15 times the outer diameter of the cable.

1. Overview
With the rapid development of information, communication cables are used on various J lines of communication systems. Our company produces metal sheathed long-distance symmetrical cables, which are suitable for comprehensive long-distance communication lines. The low-frequency four wire group of the cable can be used for audio business communication channels. The high-frequency four wire group can be used for 156KZ and below download wave communication systems. When the cable adopts a high shielding layer, it can be laid along the electrified road or in places with strong electrical interference.
