Icky-pick or icky-pic is a gelatinous cable compound used in outdoor-rated communications cables, including both twisted-pair copper cabling and fiber-optic cabling. [1] [2] "PIC" is the abbreviation for "plastic insulated cable". The cable is filled with an "icky" substance. The filled cable itself, therefore, is called an "icky PIC".
If colored white, it typically may be used for splicing neutral wires in a device box, while leaving a pigtail free for connection to a device (such as a receptacle). If colored green, the assembly is intended to be used as a grounding pigtail, similar to the feedthrough twist-on wire connectors without a permanently-attached wire.
Cross-section of direct buried cable. Direct-buried cable (DBC) is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any other cover, sheath, or duct to protect it. [1] Most direct-buried cable is built to specific tolerances to heat, moisture, conductivity, and soil ...
One or more twisted pairs, called a drop wire. The drop wires typically connect to a splice case, located in line for aerial cables, or in a small weather protected case for underground wiring, where the local cabling is connected to a secondary feeder line. These cables contain fifty or more twisted pairs.
Splice site of a copper wire. Cable sleeve (lead sleeve) for connecting paper-insulated wires Insulating sleeves. The splicing of copper wires happens in the following steps: The cores are laid one above the other at the junction. The core insulation is removed. The wires are wrapped two to three times around each other .
A rat-tail splice, also known as a twist splice or a pig-tail splice, is a basic electrical splice that can be done with both solid and stranded wire. It is made by taking two or more bare wires and wrapping them together symmetrically around the common axis of both wires. The bare splice can be insulated with electrical tape or by other means.
