1 Introduction 1.1 Scope This specification stipulates the minimum requirements for coaxial cables and antenna wires operating at radio frequencies. This specification applies to flexible and semirigid coaxial cables for low-loss, stable operation at radio frequencies and to antenna cables. These cable products are used for closed circuit television, radio communication and antenna cable connections to facilitate general communications services and surveillance throughout the NYCTA transit system. These cables are used in various outside and tunnel applications, placed in conduits, closets and other enclosures. These cables run along tunnel walls, between floors of stations and connect antenna dishes to receiving stations. They supply communications to numerous token booths and switch control locations across the system. This specification covers mechanical, electrical, insulation, and other properties that are required of these coaxial and antenna cables used by New York City Transit Authority (NYCTA) and is intended to stipulate the minimum requirements for the following cable products.

• Flexible and Semirigid Coaxial Cable - These Coaxial Cable products are used for closed circuit television (CCTV) and video communications. These cables are used in various outside and tunnel applications, placed in conduits, closets and other enclosures.

• Slotted Coaxial Antenna Cable - This radiating cable product is used to facilitate radio communications (transmission/reception) in the tunnels. The basic cable design consists of a coaxial cable with a slot in the outer conductor to allow for control release and reception of the signal (RF energy).

• Triaxial Antenna Cable - This radiating cable product is a product that uses a non-continuous outer conductor to facilitate radio communications (transmission/reception) in tunnels. The basic cable design consists of a coaxial cable with an outer conductor divided into non-contiguous segments. The RF signal can then be broadcast or be received through the gap between outer conductor semi-circular segments.

• Coaxial Transmission Line or Non-Radiating Antenna Cable - This non-radiating transmission line is utilized for transmission of RF energy between transmitting/receiving components of radio communications systems in buildings/tunnels and outdoors.

• Intrabuilding Coaxial Cable - These coaxial cables are designed for inside building applications. These cables would be placed inside building, along walls, between floors (risers), in plenums, inside closets and in ducts/conduits.

• Elevator Traveling Cables – These elevator traveling cables are equipped with video and provide signal and communications for CCTV video camera, passenger assistance intercom, and sound powered telephone for elevator maintenance. These cables consist of two coaxial units plus twisted pairs of shielded 20 AWG conductors under a single jacket sheath. The cables travel with the elevator and require flexural strength and endurance.

4.6 Elevator Traveling Cables At stations, and other transit facilities, elevator traveling-cables carry signals and communications for CCTV video camera, passenger assistance intercom, and sound powered telephone for elevator maintenance. These cables consist of 2 RG-6 coaxial units and 13 pairs of individually shielded 20 AWG conductors under a single flame retardant jacket sheath with a riser fire rating. The cables travel with the elevator and need to be physically robust and have a long flex life. It consists of the following:

1. Thirteen pairs of individually shielded #20 AWG wire stranded conductor, as per signal code cable described in Section 4.1 of NYCTA Specification TSC used for signal switching; i.e., they carry low frequency signaling information. Stranded conductors with 7 strands per conductor that are insulated with polyethylene. These cables have an inner jacket of polyethylene or non-halogen material (50 mil nominal thickness) with a 5-mil copper shield for protection and isolation from electrical noise and interference, plus a final outer jacket of low-smoke low-toxicity no halogen material.

2. Two RG-6 coaxial units meeting the applicable requirements of this specification.

The above cable shall have an operating temperature range of -15oC to +60oC. For locations outside these operating conditions, other elevator cables can be used at the discretion of the NYCTA Engineer. For example, a cable with two RG-6 coaxial units and thirteen #20AWG twisted pairs jacketed with neoprene and rubbers can be used down to -40oC.
