The Letter I

ICEA
Insulated Cable Engineers Association. The association of cable manufacturing engineers who make nationally recognized specifications for cables. Formerly the IPCEA.

IEEE
Institute of Electrical and Electronics Engineers.

Inductance
A property of a conductor which resists a change in current. It causes current changes to lag behind voltage changes and is measured in henrys.

Insulation
A material having good dielectric properties which is used to separate cable conductors. Common insulation types include PE.

Insulation Temperature Rating
A maximum temperature assigned to insulations based on laboratory tests.


Insulation Resistance
The electrical resistance of an insulating material at a specific time and condition as measured between two conductors.

Insulation Thickness
The wall thickness of wire insulation.

Insulation Voltage Rating
The nominal phase-to-phase operating voltage of a three-phase cable system.

Interconnecting Cable
The wiring between modules, between units, or the larger portions of a system. Often used in the Solar industry to describe the wires that connect each solar panel.

Interconnection
Mechanically joining devices together to copmlete an electrical circuit.

Irradiation
In insulations, the exposure of the material to high-energy emissions for the purpose of favorably altering their molecular structure. This is often used in Cross-linked Polyethylene.
