The good contact surface of wire clamp is demonstrate,proved, and can guarantee the waterproof of wire clamp cross section interface.The waterproof of wire clamp port is also focus, end
Mouth waterproof mainly processes circular groove in main line crimping pipe port, and the insulating layer installation of insulated conductor utilizes pressure in this circular groove mouth
Bonding tool will crimp tube wall and carry out effective crush seal with insulating layer, reach wire clamp port water-proof function.Pass through the two sides
The implementation of the waterproof measure in face eliminates the secondary waterproof operation after the installation of conventional wire clamp, and simplifies technique, but saved at
This.When wire clamp installation, as long as according to wire clamp length, isometric insulating layer is divested on insulated conductor, wire clamp waterproof is held
Support portion and sealing pressure contact portion are mutually installed on conducting wire, and wire clamp port is in close contact with wire insulation, utilize crimping tool reality
It applies repeatedly to squeeze and installation can be completed.In order to ensure installation effect, the water-proof skirt of wire clamp should ensure that vertically downward, could reach in this way
To good waterproof effect.
Wire clamp additional high temperature prior-warning device：Most common equipment fault is mainly several in line facility operational process is reflected in
The fever of apparatus overload high temperature, wherein interfacility link folder, disconnecting link is even more focal issue.There are workloads for conventional infrared measurement of temperature
Greatly, it needs irregularly to repeat operation, equipment dynamic control of having no idea can be exempted using novel overload prior-warning device
A large amount of thermometric workload, the device equipment installation be it is synchronous implement installation, have the characteristics that indefinite duration runs, when equipment because
For various reasons occur poor contact, overload cause generate heat high temperature when, which will start automatically, early warning Warning Mark deformation accuse
Know that the equipment has occurred and that the hidden danger such as poor contact, and the state will not change before thinking to intervene, once hidden danger is disposed,
It can think to restore normal alert status again.The prior-warning device use scope is extensive, the fixed no particular/special requirement of installation, early warning
Action is accurate, and instruction is very intuitive, is not necessarily to cumbersome other component intervention, and the temperature value of early warning can be set according to actual demand.
