Description
Technical field
It the utility model is related to a kind of rodent-resistant cable.
Background technology
Cable is typically by several or the cable of similar rope that several groups of wires (every group at least two) are twisted, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation, and cable has
Interior energization, the feature of external insulation, cable have power cable, control cable, compensating cable, shielded cable, high-temperature cable, marine electric
Cable etc., they are all made up of sub-thread or stranded conductor and insulating barrier, for connecting circuit, electrical equipment etc., the derivative of cable/new
Product uses mainly because of the requirement of application scenario, the convenience of application requirement difference and equipment and reduction equipment cost etc.
New material, special material change product structure or improve technological requirement or be combined the product of different cultivars and produce
It is raw,
Direct current cables is high with its transfer rate, and line loss is small；Adjust electric current and change direction of transfer conveniently；Installation, safeguard
The features such as expense is low, more and more apply in each field, but be used for the requirement of performance also more and more higher.
One-step silane cross-linked ethylene-propylene rubber direct current cables is fabulous with its bending property, high resilience, and with good
The features such as good electrical property, is applied to roving place, is widely used in ship, subway, nuclear power station, detects, adopts
The fields such as pick.
If, usually can be by mouse using common polyvinyl chloride or polyethylene as the cable laying of sheath in the place that mouse is rampant
Moth erosion, serious meeting cause cable breakdown, and huge economic loss is caused to society.Traditional Ratproof method is sprinkling medicine,
But effect is unsatisfactory.The cable of underground laying, preventive measure against rats are even more to be difficult to carry out.Therefore, the protection of cable is lifted as far as possible
Ability is meant a great, and the protection against rodents ability for how improving cable is become as an important problem.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of rodent-resistant cable, the rodent-resistant cable by it is interior it
It is outer once to include conductor, inner insulating layer, middle insulating barrier, external insulation layer, lapping layer and the outer jacket of repellent agent containing sporadic, it is described around
Cladding surface sets contact-type repellent agent, and the repellent agent is bonded in wrapped layer surface by amide based resins.
As a kind of preferred embodiment of the present invention, metal net layer, institute are also included between the lapping layer and outer shield
The thickness for stating metal net layer is 0.1-2mm.
As a kind of preferred embodiment of the present invention, the sporadic repellent agent is cycloheximide.
As a kind of preferred embodiment of the present invention, the contact-type repellent agent is contact-type capsaicine expelling mouse agent.
As a kind of preferred embodiment of the present invention, the inner insulating layer, middle insulating barrier, external insulation layer prepare material
Expect for one-step method silanes crosslinked EP rubbers.
The rodent-resistant cable insulation of the present invention uses one-step method silanes crosslinked EP rubbers, and multi-core type can carry out color split-phase.
The rodent-resistant cable finished product bending radius that the present invention is prepared is small, can reach 6 times of the outside diameter of cable.
The rodent-resistant cable that the present invention is prepared is provided with restrictive coating except using the TPE thermoplastic elastics with high intensity
Body, gnawing for mouse can be resistant to a certain extent and is bitten, slow down the harm of mouse trouble.It is doped with sporadic repellent agent so that old
Mouse, which is unwilling to gnaw, bites the cable, reaches rat destruction or keeps away the effect of mouse.By the way that divergence form expelling mouse agent is arranged on into restrictive coating, Ke Yijin
Possibly reduce cable failure, while after cable failure, contact-type repellent agent be set outside insulating barrier, prevent breakage again by
Gnaw and bite, greatly reduce protection against rodents effect.The rodent-resistant cable that the present invention is prepared can reach national Specification protection against rodents grade and
Flame retardant rating.
The above-mentioned of the application and other features, aspect and advantage is more readily understood with reference to described further below.
