Description
Technical field
This utility model relates to field of cable technology, particularly relates to a kind of waterproof and dampproof fire-resisting cable.
Background technology
Electric wire is the conveying energy, transmission information institute indispensable basis equipment, and from social informatization, electrified fast-developing today, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must is fulfilled for the requirement to electric wire performance of the national economy each main industry, and national economy thinks that most industry is all relevant to electric wire, and its industrial status is highly important.
Quick growth along with Chinese national economy, particularly rural area and Construction of Intercity Network transforms the quickening of paces and the flourish of various places real estate, the electric utility of China is developed rapidly, thus promoted the electrician trade matched for power industry, the especially development of wires and cables industry, the Cultivar development of electric wire presents diversified trend.Electric wire develops to multifunction from simple electric power transmission, has i.e. been attached some new characteristics respectively according to different purposes.Such as: flame retardant cable, fire-resisting cable, low smoke and low halogen cable, low smoke, zero halogen cable etc..
The requirement that blocks water power cable the most just grows up, in recent years, the cable laid in the environment of rugged environment and humidity, there is a growing awareness that the importance of water preventing ability, particularly higher in level of ground water or long-term area of heavy rainfull.Power cable uses directly buried installation mode mostly, so cable bears and comes from ground pressure and the probability damaged by external force due to anthropic factor is the biggest, water internally invades from breakage or joint, then spreads to cable two ends, causes cable electrical property to decline.Alternatively possible: cable storing, carry, lay, in running, acted on by mechanical force due to unexpected, and make cable sheath damage, water internally invades from breakage, then to the diffusion of cable two ends, causes cable electrical property to decline.When cable is installed in a humid environment, without good stop water, so cable is invaded more susceptible to moisture, thus cause the destruction of insulation, so will be greatly shortened the life-span of cable, in order to reduce Environmental Water to the impact of the various performances of cable and the infringement of cable itself, so the cable being laid in wet environment is typically necessary cable has stop water.
Cable there is also ablaze risk, and circuit is brought the biggest potential safety hazard by this.Cable still can maintain the normal work of this circuit a period of time to be the problem that current cable industry is actively studied under burning condition.It is exactly generally that, just in case catching fire, cable will not once just burn, and loop is safer.Though existing fire-resisting cable can play certain effect, but fire-resistant poor effect, when the intensity of a fire is bigger, still it is unable to reach fire-resistant function.
Utility model content
