(1) the production of extruding head too much pressure will cause peeling bad, as far as possible when extruding avoid stress by using the method of increasing the die aperture. The second water tank from the nose should be as close as possible. The water should be appropriate, maximum achieve rapid cooling.
(2) the isolation cause peeling bad bad, win...
(1) the actual cable through the long-term working current, it must be less than or equal to the permitted load current;
(2) according to the normal operation of the load current, check the network voltage loss: under normal circumstances should not exceed 7%, fault condition shall not exceed 10%;
(3) according to the startup check network voltag...
Insulation performance with irreversible decline occurring in the course of time, called the aging of the insulation.
Insulation aging of the form of various aspects, such as the increase of dielectric loss tangent, low breakdown strength, mechanical strength, or other performance.
The cause of insulation aging is complex, there is electric...
measuring insulation resistance, resistance decreases with the increase of test voltage. The higher the voltage, the higher the degree of polarization of the insulating material under test, the movement of ions to the faster, the greater the conductive currents, which will reduce insulation resistance....
Cable structure check, usually including conductor structure check, (foreign economic, pitch, monofilament diameter), extruded insulation and the sheath inspection (average thickness, the thinnest point and extruded overseas economic cooperation), and the covering layer of check, such as shielding copper wire or copper strip dimension inspe...
The Transmission Company of Nigeria (TCN) says it has lost one of its 330kV transmission lines from Sapele to Ughelli in Delta State to a fire incident caused by a petrol tanker at about 9:42am on Sunday, 9th March, 2014.
The melting and snapping of all of the line conductors between the two towers caused a loss of balance along the transmission line and th...
