Description
Technical field
The utility model relates to technical field of communication cables, specifically a kind of High-flame-retardancfireproof fireproof blocks water digital cable.
Background technique
With the high speed development of economic construction of China, electrified, network communication is constantly progressive.To the digital cable that blocks water
Market brings huge latency development space.To all increase in many big and medium-sized cities in south numerous requires high quality and height to pacify
The full communications cable, this is because the digital cable of carrying signal conveying most of outdoor that is all laid in other than route of registering one's residence,
Exposed inevitably to will receive that there was dampness in the air and the erosion of rainwater in outdoor digital cable, digital cable is in moisture and moisture content
Immersion under influence insulation performance and cause conveying poor TV signal the problem of causing network communication to be interrupted commonplace, bring simultaneously
Quite heavy loss and negative effect.Digital cable is solved to this and effectively keeps the clear communication network of signal under rain erosion
The unimpeded of network is an important topic for currently needing to solve.
As society is to the continuous improvement of security protection guarantee and communication system security requirement and national basis facility and engineering
Construction project is continuously increased, and the digital cable product that blocks water for having high-performance and highly effective and safe will be such as western developed country
Like that, it is used widely, is thus further increased to special cables such as the digital cables that blocks water in all trades and professions system
The market demand.
Digital cable carries the biography of important data, image and other information in communication system, engineered safety system
Defeated task.Due to user or engineering quotient to fire prevention block water digital cable product buying attention degree it is inadequate, be frequently run onto digital electricity
Cable causes the problem of poor TV signal network interruption commonplace under the immersion of moisture and moisture content, while bringing quite heavy
Loss and negative effect.According to previous deep lesson, so that more and more user and engineering quotient is gradually paid close attention to fire prevention and block water
The selection of digital cable type with it is proper use of, and engineering has been altered in steps in use, choosing for digital cable product
With the prevailing thought of price.Therefore, which has extensive market development prospect.
The prior art production cable flame retardance difference there is no water stop function, in a fire by flame combustion when discharge chlorination
Hydrogen and halogen harmful substance cause the aggrieved personnel in fire " secondary disaster ", and monitoring data is not able to maintain in fire
Effective conveying, while encountering moist and rainwater erosion and will cause the accident of poor TV signal network interruption.
