Embodiment Construction

[0032] As shown in Figure 1, the present invention provides a bus cable for building intelligent control system, which consists of a conductor 1, a high-density polyethylene insulating layer 2, a tape 3, an aluminum-plastic composite tape 4, a braided copper wire 5, The polymer inner sheath 6 and the nylon outer sheath 7 are composed. Features:

[0033] (1) The diameter of the conductor is 0.8mm; the insulating layer is made of high-density polyethylene with a thickness of 0.6mm, and the control accuracy is 0.003mm; the color spectrum of the insulating core is composed of four colors: red, black, yellow and white.

[0034] (2) The cable core is made of red-black, yellow-white pair twisted wires;

[0035] (3) Shielding structure, using single-sided aluminum-plastic composite tape and braided copper wire for double-layer composite shielding, the braiding density and copper wire diameter should meet the relevant standards.

[0036] (4) The outer sheath layer can be directly ext...

Abstract

The invention relates to a bus cable used for a building intelligent control system and is characterized in that the bus cable has a four-core structure, wherein the cable core is formed by twisting two wire pairs (red-black and yellow-white pairs); the cable comprises, from the inside to the outside, a conductor, a high-density polyethylene insulating inner protective layer and an outer jacket layer; one of the two wire pairs is used to transmit a DC 24 V power to the system and digital signals as well and the other one is the spare pair; the bus cable is adapted to the on-off, control, monitoring and signal information transmission of buildings; the data transmission rate of the bus cable is more than or equal to 960KB / S; and the rated voltage of the bus cable is 0.6 / 1kV. The inventive bus cable used for the control system is safe and reliable to serve as the power line for digital control lines.

Description

technical field [0001] The present invention relates to a bus cable used in a control system, more precisely to a bus cable used in a building intelligent control system, the bus cable simultaneously transmits control power and control signals. It belongs to the field of cables. Background technique [0002] With the rapid development of building electrical and power electronic technology, in modern building electrical facilities, computers have been widely used for real-time control, and digital controllers are used to directly control power electronic devices. Data collection and dynamic control of drainage, fire alarm and fire protection, air conditioning and ventilation, elevators, etc., to realize the intelligentization of building electrical control. At the same time, the diversification of various functional facilities also makes electrical installation and control circuits increasingly complex. This requires the design of electrical circuits, which can not only sat...
