Applications

 

It can be widely used in the region which general communication antenna is difficult to play a role, especially in the mobile communication system of discrete antenna cannot provide adequate coverage area, such as mountains, hills ,tunnels, subway, mines, underground buildings, shopping mall or other electromagnetic fields spread blind. In these areas, because of narrow and blocked surrounding environment, antenna coverage has been largely restricted. Leaky coaxial cable is very close to covering the object and the signal radiation direction perpendicular to the radiation environment, so it can provide the uniform field strength, therefore under these circumstances, it is the best means of wireless coverage for the wireless signal receiving device. It not only has the signal transmission function, but also has the antenna function. Through the external conductor slot control, can be controlled electromagnetic energy along the road uniform radiation out and receive incoming, to achieve coverage of the electromagnetic field strength of blind spots. So it is more and more widely used in the railway, subway, mine, military alert, underground engineering, construction of buildings and special communication network.

 

Technical characters

 

a)The inner and outer conductors are made of high-conductivity electrical copper production, which it has excellent transmission characteristics.
b) Insulator with high physical foaming insulation structure, uniform foam makes cable has low voltage standing wave radio and excellent electrical properties; it also has maintenance-free, high compressive strength, high tensile strength, excellent mechanical properties, and has good moisture resistance in humid environments.
c) The insulator of raw materials with low dielectric constant foam insulation materials, and foam up to 80%, so that in the high-frequency use, the transmission attenuation is very low.
d) It’s outer conductor with corrugated structure, so that it has good bending properties.
e) Sheath is continuous closed extrusion structure. According to user requirements, it’s material either provide PE sheath, LSZH, flame-retardant, anti-ultraviolet radiation, also provide resistance to cracking and fire jacket, to improve the safety and fire performance of cables, and the flame-retardant cable also has excellent low temperature cracking resistance. It also can produce self-supporting leaky coaxial cable.
f) Leaky coaxial cable outer sheath is specially designed with a leaky cable installation identify line, the identify line can effectively ensure the consistency of the LCX strong radiation.

 

Characteristics

 

a)Minimum bending radius of cable is 10 times of max outer diameter.
b)The environmental temperature of the cable: PE sheath is -40℃~+70℃; Halogen-free flame retardant polyolefin sheath is -25℃~+70℃.
c)c) Laying temperature is not less than -10℃.
