Different cables are used in the underground power transmission.Some are good while others are of low quality. Low quality cables cause power surges
and inconsistencies in transmission. The use of low quality cable can be dangerous and may lead to frequent power faults andblow-out of appliances,
therefore you need to choose the right power cable for underground installation. The right cable should bemade of high quality materials, and
possess features that enhance its underground power serving role. Various cables are preferred for use as an underground power serving cable,
but on this post I will share with you about the Duplex Underground Aluminum cable.
Construction
The Duplex Aluminum conductor is the same as the Duplex Aluminum Service Drop cable having two electrodes compacted
together to form one neutral electrode and one phase electrode. These electrodes are made of 1350-H19 aluminum alloy of 99.5% aluminum along
with other metals to help improve its conductivity and strength. The two electrodes are insulated using either standard polyethylene or cross-linked
polyethylene jacket. The cable has a voltage rating of 600 volts. All of the materials used in making it are tested to meets the standards
of ASTM cable specifications.
Features and Benefits
1.Like many underground cable, the Duplex Aluminum Conductor URD cable has its unique features that enables
it to operate well as an underground power distributing cable.
2.This cable has a rating of 600v which means that it can safely transmit high voltages of up to 600 volts without
breaking down.
3.Has two electrodes which are insulated with either standard or cross-linked polyethylene insulator. The
insulation by the polyethylene jacket protects the two electrodes from corrosive chemicals, excessive heat and
moisture.
4.The standard polyethylene jacket protects the electrode under moist temperatures, allowing the cable to
operate in temperatures of up to 75 degrees. While the cross-linked polyethylene jacket protects the electrode
in harsher environments of higher temperatures, of up to 90 degrees.
Applications
It is designed for underground power installation used as a secondary power transmission cable. I therefore
recommend that you give it a try for best results.
