I. Insulation mamawhna:
Cable te hian leakage leh electric shock accident ven nan insulation performance tha tak an nei tur a ni.
Environment leh hman dan dinhmun atanga insulating materials dik tak, high-temperature resistant, oil{1}}resistant, leh chemical corrosion-resistant te ang chi thlang rawh.
II a ni. Cable thlan chhuah .
A hman dan tur, a dah dan tur, leh a himna tur thil, power cable, control cable, overhead insulated cables, etc. te ang chi thil a\\angin cable chi dik tak thlang rawh.
Cable conductor-a cross-sectional area chu load current, voltage loss, leh economic current density ang chi parameter-te hmanga hriat tur a ni.
iii a ni. Laying mamawhna: 1.1.
Cable laying hian norms kaihhnawih, "Cable line dahna tur code", etc. te chu a zawm tur a ni.
Cable te chu boruak khirh tak tak, boruak lum leh vawt, humidity leh corrosiveness-a dah loh tur a ni.
Cable laying process chhung hian cable insulation layer tihchhiat loh tur a ni.
