?

?

RG type coaxial cable is produced according to SASO IEC 61196-1.
?
# # Center conductor


The center conductor shall be 21% copper clad steel with a minimum tensile strength of 440MPa and appropriate conductivity to meet the electrical characteristics indicated in Table No.1 and Table No.2.

?
# # Dielectric


Gas injected foamed polyethylene; it shall meet all applicable requirements of ASTM D 1248, shall be an insulating grade virgin polyethylene and shall not contain reground, reprocessed or recycled materials. It shall be applied concentrically and bonded to the center conductor.

?
# # 1st shield construction


Laminated shield tape (LST). The LST shall be constructed of two aluminum foils laminated to a strength member and a bonding resin on one side. The LST shall overlap the dielectric circumference by 10 percent minimum.

?
# # Braid wire


The braiding wire shall be a round aluminum wire consisting of 34 AWG(0.0063±0.01mm) using an aluminum alloy of 5056, 5154A, or 5954.

?
# # 2nd shield construction


Laminated shield tap (LST), the LST shall be constructed of one aluminum foils laminated to a strength member. The LST shall overlap the braid circumference by 10 percent minimum.

?
# # Jacket


A polyvinylchloride (PVC) compound must be used for outdoor and indoor applications. The jacket compound shall be UV stabilized, as defined in UL 1581, paragraph 1200, reference standard for electric wire, cables and flexible cords. Dimensions are indicated in Table No. 3 Jacket colors are indicated in Table No. 4.

?
# # Integral messenger


When it is required, the messenger wire shall be a zinc coated (galvanized) carbon steel wire, as specified in ASTM A641. Messenger diameter shall be 0.051±0.002 inches(1.30±0.05mm). It’s minimum breaking strength shall be 170lbf (77.1kgf). The jacketed messenger shall be connected to the coaxial member with a web that must allow separating without leaving any visible signs of splits, holes or grooves.
