What is insulation?
The cable insulation is an important part of any cable. It is made of a non-conductive material that covers the wire. It is also known as electrical insulation.
The purpose of insulation is to separate the current from the rest of the cable, keeping it inside the wire and preventing it from entering the surrounding environment.
N'otu oge ahụ, the insulation protects the wire from the harsh conditions in the installation environment and ensures its proper operation.
Insulation can be made of different materials, depending on the wire’s target application.
But overall, plastic, rubber, and fluoropolymers are the most common types of wire insulation.
Plastic Insulation
Polyvinyl chloride (PVC)
Polyvinyl chloride is resistant to moisture, fire, and abrasion and can be used in many environments. Ọmụmaatụ, acids, solvents, and ozone.
PVC insulated cables also have no taste or odor, so they are not toxic. The allowable temperature range for this material is -55°C to 105°C.
Semi-Rigid (SR) PVC
SR-PVC has similar resistance characteristics to PVC mkpuchi, but this material is better when maximum abrasion resistance is a priority.
Leaded PVC
Plenum PVC is also made of PVC, but is best suited for installation in interior areas with air circulation, dị ka elu ụlọ elu ma ọ bụ ụlọ dara ada.
Polyethylene (PE)
Polyethylene bụ ihe siri ike a na-eji mgbe a na-achọ nnukwu nnyefe ọsọ na obere ikike.
Polyethylene bụkwa nhọrọ kacha mma maka mkpuchi eriri coaxial. Ihe a na-egbochi ire ere, mgbawa, na ihe mgbaze, ma na-arụ ọrụ na okpomọkụ n'etiti -65°C na 80°C.
XLPE (polyethylene jikọtara cross) mkpuchi bụ subụdị nkịtị nke mkpuchi polyethylene.
Polypropylene (PP)
PP nwere ihe ndị yiri ya na PE mana a na-ejikarị ya na gburugburu ime ụlọ. Okpomọkụ a na-anabata maka mkpuchi a bụ 30°C ruo 80°C.
Polyurethane (PUR)
PUR bụ ihe na-agbanwe agbanwe nke a na-ejikarị eme ihe maka eriri na obere okpomọkụ na gburugburu mmiri. Ọ na-eguzogide mmiri, kemikal, na abrasion ma nwee oke okpomọkụ na-arụ ọrụ nke -60°C ruo 90°C.

Neoprene (Polychloroprene)
Neoprene na-eguzogide abrasion, mmanụ, na ihe mgbaze. Ihe mkpuchi a na-eme ka waya na-adịgide adịgide.
Ethylene-Propylene Rubber (EPR)
A na-eji EPR eme ihe na eriri voltaji dị elu – ọ na-agbanwe ma na-eguzogide ọtụtụ mgbakasị ahụ. oke okpomọkụ a na-anabata maka mkpuchi eriri EPR bụ -50C ruo 160C.
Ethylene-propylene-diene monomer (EPDM)
EPDM na-eguzogide ọnọdụ ihu igwe siri ike, okpomọkụ na abrasion, yana ịbụ dielectric siri ike na mgbanwe. Ọnọdụ okpomọkụ ya na-arụ ọrụ bụ -55ºC- ruo 50 ° C.
Silikoni
Silicone bụ ihe sịntetịt na-agbanwe agbanwe nke a na-ejikarị eme ihe ihe mkpuchi roba. Ihe a bara uru karịsịa na ebe okpomọkụ dị elu n'ihi na ọ nwere ike iguzogide okpomọkụ ruo 180 ° C..
Fiberglass
Igwe eriri na-eguzogide mmiri na kemịkalụ.
Igwe mkpuchi iko a nwere oke okpomọkụ na-arụ ọrụ nke 482 Celsius ma a na-ejikarị ya na kilns, nhazi aluminum, na ọgwụgwọ okpomọkụ.
Styrene-Butadiene Rubber (SBR)
SBR nwere ihe ndị yiri ya na neoprene mana a na-ejikarị ya na eriri Mil-C-55668.
Ihe mkpuchi fluoropolymer
Alkoxy perfluorinated (PFA)
PFA bụ ihe siri ike na, ya mere, ihe mkpuchi na-adịgide adịgide nke enwere ike iji na oke okpomọkụ (site na -65°C ruo 250°C).
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene bụ ihe na-agbanwe agbanwe nke thermoplastic bụ okpomọkụ, mmanụ, mmiri mmiri, na chemical eguzogide.
Okpomọkụ a na-anabata maka ihe a bụ -70°C ruo 205°C.
Fluorinated ethylene propylene (FEP)
A na-ejikarị FEP na jaket ala na eriri ndị agha n'ihi oke ọkụ ọkụ ya na ike nnyefe data dị mma..
Polyvinylidene fluoride (PVDF)
A na-akpọ PVDF dị ka Kynar – ọ na-eguzogide ọtụtụ mgbakasị ahụ, gụnyere ire ọkụ. Ọ na-agbanwekwa ma ọ dịghị arọ, nke na-eme ka ọ dabara nke ọma maka ikuku ime ụlọ.
