The only things can be considered waterproof rated conductors are the lv abc accessories for nothing other than LV ABC insulated conductors. The dielectric behavior has been analyzed to be about 6kV under water. IPC shall be designed in such a manner to tap off LV ABC conductors that comply with HD 626 standards. A single lightning action to the tap and the main conductors will have them both connected without eliminating the insulation.
A housing that is insulated must in one way or the other encapsulate all the live components and it must be an anti-Ultraviolet stabilized black thermoplastic. In addition, it must be very much appropriate for application by an installer that is working single-handedly with 13 mm hexagon wrench. Peeling off the insulation is by all means avoided. The copper conductors that will be used to tap it must be equipped with flexible end caps and shear heads. It is suitable for aluminum conductors.
There is the provision of a separate tightening Verizon under the reference KZ31, just so as to have the tap line disconnected without having to remove the connector.
The adapter can be installed on the left side or on the right side.
This version is comprised of the above connector in which a specific adapter is fitted. This adapter is fitted with a 13 mm shear bolt (10 Nm). The conductor should be stripped.
The connector has similar features as above with the exception that the tap can be reinstalled after it has been removed.
This connector has the same feature as above with the exception that the tap conductor can be re-installed after removal.
A cable duct serves to protect the cable along its entire length. It is a tube where the cable is inserted. The material of a conduit is chosen according to its specific properties, such as resistance to humidity, shock, radio interference, etc.
A duct is routinely used when the cable may be exposed to hazardous substances, chemical vapors or other hazards that could damage it. In this type of application, the conduit is usually sealed.
The routing and connection of cables are part of the installation methods. The cables must be supported by chutes and made accessible by covers. In some cases, the routing and connection designate the means used to hold the cables in position when they are not embedded in walls. These means include rectangular chutes, cable carriers, and cable trays, in which the cables are laid.
Cable glands are accessories installed at the end of the cables. They serve to stabilize the cable in the crossed equipment. This may be large equipment used to connect fiber optic cables out of the ocean, or a small system that distributes cable TV signals in multiple boxes.
Cable glands can be made of materials specifically designed to withstand environmental hazards, such as salt water, hydrocarbons, etc. They, therefore, make it possible to use shielded cables in dangerous zones.
Cable Grommet or voltage reducer
A voltage reducer is a device that serves to reduce traction, or other mechanical force, experienced by a cable. Various accessories are available to protect the cables in this way, such as cable glands, already mentioned.
The grommets help to reduce the tension on a cable, but their role is primarily to protect the shield against the risk of friction or cut. Generally circular, the grommets are designed to be inserted into holes drilled in brick, wood, sheet metal, etc. to allow the passage of the cable without touching this material. The sizes and materials of the grommets are extremely variable, but the rubber dominates.
An actuator cable, also called a sensor cable, is a special type of cable that serves both to power a device and to carry actuator/sensor signals in both directions. This type of cable thus provides current and control signals. In this category, a sub-group includes the mechanical actuator cables that are used to transfer the manual controls of the operators to the mechanisms.
An actuator cable usually contains three or four high-resistance conductors. They supply power to the actuator mentioned above. Three-conductor cables are most often used for single-phase power systems. Four-wire cables are reserved for three-phase power supplies.
A conduit is an independent protection that allows to group several insulated conductors. It can be a rigid or flexible pipe. The ducts can replace the normal outer sheaths of the cables. They facilitate and accelerate cable modifications and changes. They are widely used in industrial and commercial installations. Their types are varied and include various materials, such as steel, stainless steel, soft plastic and PVC.
