Na ba opérations ya installation électrique mpe ya entretien, sélection ya matériel mpo na ruban isolant électrique ezali directement na impact na sécurité électrique mpe na fidélité ya construction. Ba matériaux ya bande isolant oyo ekeseni ezali na ba propriétés physiques mpe chimiques unique, esengaka match spécifique oyo esalemi na scénario ya application spécifique.
Polyvinyl chloride (PVC) tape is currently the most widely used insulating material. Its advantages lie in its excellent electrical insulation performance (breakdown voltage exceeding 6000V), good weather resistance, and flexibility. PVC tape, whose hardness is adjusted by adding plasticizers, is suitable for insulating conventional low-voltage lines. However, it is susceptible to softening and deformation in long-term high-temperature environments (>80 degré ).
Caoutchouc-Basé self-Bande adhésive, oyo esalemi na caoutchouc naturel to caoutchouc butyle, elakisaka ba propriétés ya ductilité mpe ya scellement ya malamu mpenza, yango wana ebongi mingi mpo na ba joints ya câble ya imperméabilisation. Ba propriétés na yango ya mémoire élastique ekoki ko compenser stress oyo ewutaka na expansion thermique mpe na contraction ya ba conducteurs ya métal. Kasi, caoutchouc ekoki kozwa maladi ya ozone mpe esɛngaka kozala na couche ya kobatela na libándá na bisika oyo ezali na ba rayons UV makasi.
Bande ya film ya polyimide (PI) ezali matériel isolant ya likolo{0}}end na intervalle ya résistance ya température ya -269 degrés na 400 degrés mpe makasi ya diélectrique eleki 20 kV/mm. Esalemaka mingi na ba environnements ya makasi lokola aérospatiale. Kasi, likambo na yango ya mabe ezali ete eloko na yango ya makasimakasi esalaka ete ezala malamu te mpo na kozinga bisika oyo ezali na mindɔndɔmindɔndɔ oyo ezali kogumbama.
Momesano ya ingénierie électrique ya mikolo oyo ezali kopesa ntina na likanisi ya "Bobateli ya biloko," ndakisa, kosalela structure multi-layer oyo ezali na ruban PVC lokola base, ruban ya caoutchouc lokola scellant, mpe film ya PI lokola renforcement. Ntango ozali kopona ruban, esengeli kotalela ba paramètres ya ntina misato : niveau ya tension ya fonctionnement (oyo e déterminaka épaisseur ya insulation ya base), cycle ya température ambiante (oyo ezo affecter coefficient ya vieillissement thermique ya matériel), mpe ba conditions ya stress mécanique (lokola fréquence ya vibration). Kopona matériel ya bande isolante oyo ebongi ezali na ntina mingi mpo na kosala ete ba systèmes électriques ya molayi ezala ya molai-term stable.
