Application

The following applies to IGHZ analog and high speed digital signal transmission;
Used in TV, radio signal control and information transmission;
For fixed or mobile radio communication signal transmission using similar technology and electronic means; specifically for video surveillance systems, public antenna, CCTV systems, radio communications, broadcasting equipment, transmission systems, and unidirectional control system or high frequency machine internal wiring.

Cables Features

Using temperature between -40℃ and+ 65℃, when the temperature is 40 + 2℃, 98%, install the laying temperature not less than 15℃. Allow the minimum bending radius: indoor use not less than five times the cable diameter, outdoor use should not less than 10 times the cable diameter.

Model composition and representation >>

Monitor video cable is a wire and cable for connecting surveillance cameras and reality terminal (computer or monitor, etc.), whose role is to transmit image data captured by a surveillance camera. Monitor video cable is a coaxial cable, also known as coaxial video cable, letter code is SYV, therefore, also called SYV cable or  video coaxial.

Surveillance video line has a good anti-jamming, uniform impedance; Good moistureproof ability, long service life; Low attenuation, low capacitance; High transmission, stable structure, etc, the current application is very extensive . At the same time it is closely related to our life, like the community, office buildings, streets, and so on ,we can see surveillance cameras;  of course ,  is behind with the surveillance video line. So, is to monitor video line provides us a good security.

Depending on the size and function, control lines, respectively: SYV series, TSYV series, SYWV series of several major types, the following is a detailed description of several major types— —

Introduction:

SYV, full name: copper core solid core polythene insulated PVC sheathed coaxial radio frequency cable, is made of layers of insulated wire wrapped around the central copper conductor cable. Allow the minimum bending radius: indoor is not less than five times the cable diameter, outdoor not less than 10 times of cable diameter.

Product description:

TSYV elevator with integrated cable, also known as the elevator video line, mainly is suitable for the elevator monitoring system of video transmission and control signals. Elevator comprehensive cable is made from a mix of coaxial cable, there is a strengthening steel wire and nylon rope, and fibrous tissue, outer sheath with super soft PVC material, effectively increase the tensile strength and flexibility. Has a long service life, stable video transmission model, high resolution, etc.

Product basic parameters:

Performance:

Due to the narrow space of the elevator is an almost closed, and elevator control, lighting, fan, etc. A lot of cable, so add difficulty to the video cable wiring, according to the practical analysis on the choice of the elevator with integrated cable should follow the following principles.
1. meet the tensile strength: elevator half is used to extend cable, high-rise elevator up to more than 100 meters, one hundred meters of cable is nearly hundred kilograms of weight, so the cable must have enough tensile strength. Now in the market for messenger flat composite elevator monitoring special cable, the cable will be video coaxial cable, power cord, cable and steel strand composite together, make it a flat ribbon cable, so that the whole cable tension by the steel strand to inherit, the tensile strength is very good, not in the elevator running, because gravity pulled signal cable.
2. good electrical parameters: the cable as the elevator up and down movement of the process, there will be a middle segment by the gravity bending deformation, caused by the impedance of the cable and the distributed capacitance electric parameters, such as changing. When quality is bad of cable force deformation, parameter change is big, it will cause the impedance mismatch, the attenuation increases and generate video signal reflection, it is to cause a decline in video signal SNR, video interference, so try to choose good shielding, wire diameter thick video cable, to prevent interference signal "invasion".

Introduction:

TSYV camera with integrated line, more applied to close a number of transmission system, and applies to close monitor or computer video display system connection and engineering thread connection. Anaerobic OFC copper conductors, it adopts PE solid insulated, independent block structure, can effectively reduce the interference and guarantee the signal transmission with high speed, ensure results show more clearly; By two coaxial cable core power collocation, at the same time, on the transmission signal and power supply each other, and convenient in the structured cabling system.

Product description:

SYWV, commonly known as TV antenna, through physical foam, belong to one of the coaxial cable of the radio frequency. Physical foaming coaxial cable is a kind of air insulated coaxial cable, the inner conductor adopts the oxygen-free copper wire, insulation consists of polyethylene by the physical foaming make its tiny closed pores with each other. it is Firmly bonded  between insulation and the inner conductor.
Such as SYWV75-5
S: radio frequency (rf), Y: polyethylene insulation, W: physical foaming, V: PVC sheathed
75:75 ohms, 5: cable diameter is 5 mm, 1: on behalf of the single core

Installation conditions:

Operating temperature（℃)：-40℃～+65℃
Allow the minimum bending radius: indoor use not less than five times the cable diameter, outdoor use should not less than 10 times the cable diameter.
