MSLYFYVZ-75-9 mine fire leaky coaxial mine communication cables, communication cables leak mine, mine explosion-proof cable, intrinsically safe communication cables, flame retardant mine leaky leaky coaxial cable This product uses is the "swing around the stack style" of the latest international structure leaky cables, it excellent performance, reliability, and can be efficiently transmitted and can radiate radio frequency signal. In the tunnel, it produces a radio wave signal strength higher than normal leaky cables 15db, has good lateral coverage, went blind in effect, as compared to other similar products more excellent effect. A. Cable Impedance: 75Ω B. Standard length of 400m Operating characteristics 1, the use of frequency: 1GHz these two, the use of ambient temperature: -25 ℃ ~ 70 ℃ 3, laying temperature: not lower than 0 ℃ 4, bending radius: not less than 15 times the cable diameter. 5, this product has low attenuation and low VSWR and excellent water tightness, air tightness, flame retardant characteristics. Note: 1, the outer diameter of the cable can also be customized. Procurement KTL101-S mine handheld radio must take certain precautions, still need to be verified before purchase some technical problems, there is a world of small coal Mr. Zhu secrecy, have any questions feel free to call, 24 hours a day!
