Abstract

DC60 (09/07/40) Communication cables with special electrical characteristics. And that meets combustion requirements for the use of pipelines. Wiring with a core made up of a pair of twisted wires A pair of spirals or Rather than having a first layer of insulation made up of Suitable materials such as high-density polyethylene, the core is encased by an inner sheath made of low-smoke polyvinyl chloride materials, as an alternative or Inner shell The core may be encapsulated by the wrap. Core cladding with adequate electrical properties and combustion / ignition resistance characteristics. The inner shell will Is wrapped up by The outer shell consists of a material that has the Excellent heat / flame resistance, but may be less than the highest electrical properties like thermoplastic. Halogenated polymers, for example, many core polyvinyl fluoride materials are encapsulated by a dedicated inner core encapsulation and / or inner shell. May be encapsulated by Outer shell Communication cables with special electrical characteristics and that meet combustion requirements. For pipe use Wiring with a central core Made up of a pair of twisted wires One or more pairs of strands with a first layer of insulation made of Suitable materials such as high-density polyethylene, the core is encased by an inner sheath made of optional low-smoke polyvinyl chloride materials or outside. From that inner shell The core may be encapsulated by the wrap. Core cladding with adequate electrical properties and combustion / ignition resistance characteristics. The inner shell will Is wrapped up by The outer shell consists of a material that has the Excellent heat / flame resistance But may be less Highest electrical properties as thermoplastic Halogenated polymers, for example, many core polyvinyl fluoride materials are encapsulated by a dedicated inner core encapsulation and / or inner shell. May be encapsulated by Outer shell
