Buried bite-proof communication cable HYA23 is a cable for transmitting electrical information

Buried bite-proof communication cable HYA23 is a cable for transmitting electrical information. Divided into local telephone cables, long-distance communication cables, local office cables connected between racks and racks or racks, telephone cords used as telephone equipment connecting lines, integrated communication cables, and shared antenna TV cables, RF cables and optical cables. For telephone communication lines, integrated wiring systems, cable television systems. This section mainly discusses commonly used local telephone cables in buildings. There are mainly two types of indoor common telephone cables: HYA-type comprehensive sheath plastic insulation local telephone cable and HPVV copper core full PVC distribution cable. Buried bite-proof communication cable HYA23 can be buried outdoors or piped. Indoors can be overhead or laid along walls. HPVV copper core full PVC distribution cable for indoor use can be piped or laid along the wall. The main nominal section specifications are: 0.4; 0.5; 0.6mm2. The number of pairs of HYA cables is: 10;20;30;50;100;200;400;600;900;1200;1800;2400. The number of pairs of HPVV cables is: 5;10;15;20;25;30;50;80;100;150;200;300.

Buried bite-proof communication cable HYA23 Application: It is applicable to the transmission system between the remote optical network unit and the user, and the subsystem for transmission between buildings in the building wiring system. The maximum transmission frequency is 30MHz and 100MHz respectively.

Construction and installation points Specific construction practices are described in the National Building Standard Design Atlas 94X101 Indoor Communication Line Installation and 94X102 Underground Communication Cable Laying.

Buried bite-proof communication cable HYA23 advantages introduction:

1. Generally buried in the soil or laid in the indoor, channel, tunnel, the insulation distance between the lines is small, without poles and towers, covering a small area, basically does not occupy space on the ground;

2. It is affected by the weather conditions and the surrounding environment, the transmission performance is stable, and the reliability is high;

3. Has more favorable conditions for the development of ultra-high pressure and large capacity, such as low temperature, superconducting power cables;

4. Larger distributed capacitance

5. The maintenance workload is small;

6. The possibility of electric shock is small.

The rare-earth metal thick film heating technology is one of today's most innovation and forward-looking solution for electric heating field.The thick film heating tubes/elements are produced by screen-printing dielectrics (5 layers), resistance (palladium-silver), conductor (silver) and isolation glazes on the substrate and sintered 7-9 times at temperature over 900℃.

 

With 5KW Thick Film Heating Tube simple tubular structure, it can heat water flow inside the tube. Electric Circuit printed on tube surface, to heat the water flow inside. For applications where space is limited, this simple profile heater offers high thermal power density and fast response times to heat up or cool down (due to low thermal mass).

 

JIEDA company can supply products according to customers' drawings and offer our clients reasonable prices. Our company also can develop heating solutions and products together with customers.Those new types Thick Film Heater Tubes are special designed for Through-Flow applications, such as instant water heaters, instant water flow heater under sink, commercial vendor and industrial water flow heater.
