Why should the transmission line use Double Circuit Tower?

1. Conceptually: Single circuit refers to a load has a power supply circuit; A double loop is a circuit that has 2 power supply in one load.

In fact, the most important protection of electricity reliability …

2. The general area important substation, all uses the double return line power supply.

With his double circuit is a unit of electricity with two power supplies simultaneously erected over.

3. Dual-split conductors are also used in transmission lines.That is, one phase is composed of two wires, the aim is to increase the amount of power transmission, reduce the integrated impedance of the system, strengthen the connection of the grid, make it stronger.

4. The same tower double back transmission line, is the two ends of each other for power supply, usually sometimes as a standby, such a double loop, is generally the form of ring nets, is a to B, B to a power supply mode. Also has the same tower double return tower to erect the tr.ansmission line, in order to transmit the bigger transmission power!

The foundation is larger than the single Circuit foundation, naturally in order to guarantee and improve power supply reliability, balance load. Good safety performance at the same time the transmission power is large.

 

Jielian provide the double circuit and multi circuit transmission lines for our esteemed clients. The Tower Line work involves Survey, check survey, and span calculations essential for tower

extensions. Moreover, Tower designs and prototype approval is done. The towers are for 35KV, 66KV, 110 KV, 132 KV, 220 KV, 400 KV, 500KV, 750KV, and 800KV.

A double-circuit transmission line has two circuits. For three-phase systems, each tower supports and insulates six conductors. Single phase AC-power lines as used for traction current have four conductors for two circuits. Usually both circuits operate at the same voltage. In HVDC systems typically two conductors are carried per line, but rarely only one pole of the system is carried on a set of towers.

Both tubular and lattice steel towers can be designed so as to support two circuits of electrical current. Double-circuit towers hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally.

Jielian is one of the few manufactures who assemble a face of double circuit transmission tower. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies.

After fabrication all double circuit transmission tower are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.
