Modern ịkwanyere teepu nwere ndị na-esonụ e ji mara: obosara bụ site 13 ruo 20 mm na a ọkpụrụkpụ nke na-erughị 0,13 mm. Na thicker mmachi, nke ukwuu ga-ya-egbochi ihe Njirimara. Mkpa e ji mara nke teepu bụ:

1. High voltaji mmebi. Ọtụtụ na-emepụta na-egosi elu-etoju nke dielectric Njirimara nke etere, nke mere na ha nwere ike idi elu voltaji.
2. Na-ekwe nkwa àgwà nke mkpuchi ma ọ bụrụ na mkpuchi na-nyere na abụọ ma ọ bụ atọ n'ígwé.
3. N'ihi ụfọdụ thermostability nke ịkwanyere teepu nwere ike-eji ihe karịrị a obosara okpomọkụ nso, ka ókè.
4. Good adhesion. Ọ na-nyere mkpebi ziri Nchikota oke ọkpụrụkpụ ụdị nyagide.
5. The ike na ndakpọ voltaji. Magburu onwe ekwe ojiji nke teepu na eletriki ọrụ ọ bụla complexity.
6. Ike ọdụdọ. Ha na-eme ka na-agbanwe ike nke teepu.
7. Fire-agha Njirimara. Mezie a na-eji mgbe na-ejizi eletriki wires, n'ihi ya, ọ dị mkpa ka ewepu ihe ize ndụ nke ọkụ ma ọ bụ electric ujo.

Ichi, ma etere na acrylic nyagide mkpuchi adhesion na-aghọ elu n'oge ọrụ, mgbe roba mkpuchi na-egosi ya ihe nyagide Njirimara fọrọ nke nta instantaneously. The pụrụ iche atụmatụ a-egbochi ihe onwunwe na-ezo inflammability na gbawara, ma n'oge combustion teepu nwere ike hapụ nsi.

Ọdụdọ egbochi ihe Njirimara enye ikike iji nagide teepu ruo 5000 volts voltaji, nke bụ zuru ezu maka ọrụ n'ụlọ na-arụ ọrụ.
