Glossary of Wire & Cable Terminology
H - Abbreviation for henry (unit of measure of inductance).
H-FILM® - High temperature polyimide Kapton® film. H-FILM® and Kapton® a re trademarks of the DuPont de Nemours Co.
HALAR® - Ethylene chlorotrifluoroethylene or ECTFE copolymer. A high temperature insulation. Halar® is a trademark of the Allied Chemical Co. See ethylene chlorotrifluoroethylene.
HALOGEN - Any of the five elements fluorine, chlorine, bromine, iodine, and astatine that form part of group VII A of the periodic table and exist in the free state normally as diatomic molecules.
HAM - An amateur radio operator.
HARD DRAWN - The conductor is work hardened in the drawing process. Hard drawn refers to the temper of conductors that are not annealed after drawing.
HARNESS - An arrangement of wires and cables, usually with many breakouts, which have been tied together or pulled into a rubber or plastic sheath, used to interconnect an electric circuit.
HASH MARK STRIPE - A noncontinuous helical stripe applied to a conductor for identification.
HD - Abbreviation for high density.
HDP - Abbreviation for high density polyethylene. Compared to PE (polyethylene) it has higher abrasion resistance, higher weatherability, and lower flexibility at room and low temperature. Also abbreviated as HDPE.
HDPE - Abbreviation for high density polyethylene. Compared to PE (polyethylene) it has higher abrasion resistance, higher weatherability, and lower flexibility at room and low temperature. Also abbreviated as HDP.
HDXLPE - Abbreviation for high density cross-linked polyethylene.
HEAD SET CORD - A very flexible cord used for communication equipment usually 24 AWG to 22 AWG multi-conductor. Usually made with Buna insulation, rubber or Neoprene® jacket; sometimes the outer jacket is a cotton braid. The conductor may be bare copper or cadmium bronze. Neoprene® is a trademark of the DuPont de Nemours Co.
HEAT AND PRESSURE CURE - Uncured rubber or rubberlike compound that is usually cooked in a mold under high pressure at a given temperature. The pressure, temperature, and time required for curing depends upon the type of compound used.
HEAT ENDURANCE - The time of heat aging that a material can withstand before failing a specific physical test.
HEAT SEAL - A method for sealing a tape-wrap jacket by thermal fusion.
HEAT SHOCK - A test to determine stability of a material by sudden exposure to a high temperature for a short period of time.
HEAEAT SHRINK - A material that shrinks when heated. Heat shrink tubing is used for insulation, sealing, and protecting wire connections, terminations, and splices.
HEAT SHRINK SPLICE - Same as Fusion Splice except the splice is protected within a heat shrink tube.
HEATER CORD - Flexible stranded copper conductor, cotton wrapped, rubber insulation, and high temperature roving. For indoor use on household appliances such as flat irons, coffee pots, toasters, heaters, and soldering irons.
HECTO - A prefix to a unit, denoting a multiple of 100 (102) of that unit.
HELICAL STRIPE - A continuous spiral stripe applied to the insulation of a conductor for the purpose of circuit identification.
HELIX - Something spiral in form; a coil formed by winding wire around a uniform tube; a curve traced on a cylinder or cone by the rotation of a point crossing its right sections at a constant oblique angle.
HENRY - The unit of measure of inductance. It is defined as the inductance of a circuit in which a counter electromotive force of one volt is generated when the current is changing at the rate of one ampere per second. Abbreviation H.
HERTZ - A term replacing cycles per second as an indication of frequency. Abbreviation Hz.
HF - a) Heavy Formvar Magnet Wire. Soft bare copper wire with baked synthetic insulation overall. b) Abbreviation for high frequency. See frequency band.
HF/LSLS/LT - Abbreviation for halogen-free, low smoke, low toxicity.
HI-POT (HIGH POT) - A test designed to determine the highest potential that can be applied to a conductor without breaking through the insulation.
HIGH FREQUENCY - See frequency band.
HIGH TENSION - See high voltage. Abbreviation HT.
HIGH VOLTAGE - A wire or cable with an operating voltage over 600 volts.
HL - CSA mark used to identify cables which comply with the Hazardous Location performance requirements of CSA C22.2 No. 174 specification.
HMWPE - Abbreviation for high molecular weight polyethylene.
HOOK-UP WIRE - A wire used for low current, low voltage (under 1,000 volts) applications within enclosed electronic equipment, usually 12 AWG and smaller.
HOT TIN DIP - A process of passing bare wire through a bath of molten tin to provide a coating.
HPD - Heater cord, rubber, and high temperature barrier, insulated with an overall braid.
HPN - Heater cord, Neoprene®, parallel, two conductor.
Neoprene® is a trademark of the DuPont de Nemours Co.
HR - Abbreviation for high resistance wire.
hrs - Abbreviation for hours.
HT - a) Abbreviation for high tension. See high voltage. b) Abbreviation for high temperature.
HW - Type designation for heavy wall, 2,500 volt electronic hook-up wire to MIL-W-76.
HYGROSCOPIC - Readily absorbing and retaining moisture.
HYPALON® - A synthetic rubber, chlorosulfonated polyethylene (CSPE or CP). Hypalon® is a trademark of the DuPont de Nemours Co. Resistant to oxidation by ozone, sun, weather, heat, and chemicals, rated 90° C.
Hz - Abbreviation for Hertz. See Hertz.
