Contaminants: Tape chunglama conductive dust emaw salt spray emaw hian conductive bridge a siam a, leakage current path a siam a ni.
High-voltage electrical equipment-ah chuan PTFE tape-te dielectric strength hi fixed value ni lovin application condition-ah a innghat nasa hle. Corona-resistant grade tan chuan thil siamtute chuan PTFE matrix-ah hian inorganic filler mica emaw ceramic particle emaw an dah tel fo thin. Heng filler te hian micro-interface tam tak an siam a, chu chuan charge concentration a tidarh a, partial discharge activity a titawp bawk. High-voltage inverter motor (eg, 6kV to 10kV class) atana PTFE tape thlan dawnin corona-resistant PTFE tape thickness 0.18mm tal hman a tha a, actual operating temperature hnuaiah partial discharge inception voltage (PDIV) chu verify a tha a, PDIV hi room temperature nena khaikhin chuan 150°C-ah 20-30% in a tlahniam tlangpui a ni.
Thermal Stability a awm theihna tur hlauhawm
High-Temperature Aging: PTFE tape te hian a tlangpuiin 260°C temperature chhunzawm zel ah stab takin hna an thawk thei. Mahse, a lumna chu 250°C aia sang (a bik takin 300°C hnaih) a nih chuan molecular chain te chu a chhe tan ta a ni. Hetiang decomposition hian dielectric strength nasa takin a tihtlem a, insulation failure hazards a siam bawk.
Thermal-Oxygen Synergistic Effect: Temperature sang leh oxygen inzawmkhawm hian material aging a ti chak hle. Khaw lum leh vawt hnuaiah chuan voltage resistance performance chhiatna hi dry heat chauh nena khaikhin chuan 30% atanga 50% in a pung thei a ni.
Oxygen supply tlem zawkna hmuna switchgear emaw transformer windings inkharkhip-a PTFE tape hman a nih chuan thermal aging behavior hi open-air condition nen a danglam hle. Zirna hrang hrangah chuan PTFE hian nitrogen-a thermal decomposition rate chu boruak temperature inangah aiin hmun sawma ṭhena hmun khat vel a ni tih a tarlang. Hei hian a awmzia chu hermetically sealed high-voltage components tan chuan PTFE tape hian 260°C aia sang deuhah pawh service life rei zawk a nei thei tihna a ni. Mahse, decomposition a tan chuan by-product carbonyl fluoride leh perfluoroisobutylene te hi a toxic hle a, metal contact-ah pawh a tichhe thei hle. Chuvangin, application temperature chu decomposition threshold hnuai lam deuha awm reng a pawimawh hle – critical high-voltage insulation atan safety margin 30-50°C neih a tha.
Signal Attenuation leh Distortion: Standard PTFE-a dielectric constant (Dk) chu 2.0 atanga 2.6 inkar a ni. Dk-a deviation tam lutuk nei product hian transmission laiin high-frequency signal attenuation leh distortion a thlen thei a – RF leh microwave application tan chuan thil pawimawh tak a ni.
Heat Generation Effect: PTFE hian dielectric loss tangent (tan δ) a nei tlem hle a, a tlangpuiin 0.0025 hnuai lam a nei. Mahse, loss factor a san lutuk chuan (i bawlhhlawh emaw, processing dik lo vang emaw) chuan high-frequency electric field hnuaiah heat nasa lutuk a siam chhuak ang. He self-heating effect hian material aging a ti chak a, thermal runaway a thlen thei bawk.
