scope:

This sectional specification relates to IEC 62255-1. This standard is applicable to filled cables having a metallic screen over the cable core, a polyethylene jacket, copper conductors, and solid or cellular insulation. These cables are typically available in 6 to 300 pair. These cables are suitable for direct burial, installation into ducts, or installed aerially by lashing to a support strand. They may also be self-supporting by incorporation of an integral suspension strand. The cables covered by this specification are differentiated by bandwidth and are classified by having a maximum reference frequency of 30 MHz, 60 MHz, or 100 MHz.
