As far as safety is concerned, it is recommended that you choose the right cable for power transmission to avoid any power blow out or fault. The choice of the type of cable to use goes hand in hand with the method of transmission used. For the underground power transmission method, I will share with you about the single conductor aluminum cable type UD in this post. This cable has unique features and materials that enhance its underground power serving purpose.
It is made of aluminum compressed at 1350-H19, customized with compacted trapezoid wire to decrease its circumference. Which means, it’s not as bulky as many other cables out there in the market. However, like many other cables, the single conductor aluminum type UD cable has an insulator made of polyethylene compound which has the ideal insulation attributes.
Features of the Single Conductor cable
1.This cable has an insulation made of plastic polyethylene, which is non-biodegradable making it to last longer as
it keeps the cable away from rotting under the soil.
2.The polyethylene insulation is strong and protects it from unnecessary cuttings, abrasion, high heat and
corrosive chemicals.
3.600 volts rating which means it accommodate heavy loads of power of up to 600 volts.
Applications
This cable is designed to be used as a secondary power distributing cable, and commonly deployed in our residential places. The secondary distribution occurs when the voltage of power transmitted through the transformer is lowered to a safer voltage for use in our households. The Single Conductor Aluminum Type UD cable is meant for underground power distribution, because of its durable plastic polyethylene insulation which make it withstand the rocky underground obstacles.
An electric transmission cable with such resilience features and durable materials, can better solve the problem of frequent power faults and blow out of appliances. I guarantee that it will give you quality service.
