1. Nguzogide DC nke onye na-eduzi eriri emechara (Klas R) (dịka iwu GB3956 si dị) ga-ezo aka na Mgbakwunye A Tebụl 2;

2. Ịnabata ihe mkpuchi mmiri na ihe mkpuchi pụrụ iche nke mbata;

3. Usoro nhazi na mmepụta pụrụ iche;

4. Na 20 ℃, ihe mgbochi mkpuchi agaghị adị obere karịa 50M Ω/KM;

5. Eriri emechara ga-anagide ule voltaji AC nke 50Hz, 3.5 kV, na nkeji ise na-enweghị mmebi.

Ihe ndị a na-ejikarị eme ihe maka eriri mmiri na-enweghị mmiri bụ ụfụfụ polyurethane, ụfụfụ copolymer na ụfụfụ mejupụtara. A na-atụnyere njirimara na ojiji ha dịka ndị a:
