ACSR Overhead Bare Aluminum Conductor

Standards and Scope of Application
The products are used for aerial electric power transmission according to the standard ASTM , IEC , BS , CSA , NFC , and so on

Specific property for using
1.The permissible long-time operating temperature for aerial conductor is 70 C 
2.For long-span application in harsh environment such as heavy icing , the biggest stress of the cable at the lowest point on the span curve shall not exceed 60% of its breaking load.
3.When connecting conductors , the conductor near the connecting tube can't be prominent. Otherwise , the force on the operating conductors will be unbalanced after connectors are pressed . The connecting tube should be plated by moistureproof paint in order to avoid corrosion.
4.In order to meet conductor-to-earth or conductor-to-building distance requirement during installation , the conductor stress can be 10%~15% higher than its permissible normal tension .

DESCRIPTION
The conductor consists of hard drawn aluminum wires and zinc coated steel wires built up in concentric layers . 
The centre wire or wires are zinc-coated and the outer layer or layers are alumnum wires .
The wires are stranded in successive layers in opposite direction . 

STANDARDS
Construction as per ASTM , IEC , BS , DIN , CSA , NFC ,and so on.

APPLICATION
ACSR bare conductors are used for overhead high tension power transmission lines having long spans .

As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.

Short circuit protection:The following test shall be performed. Charge batteriesas specified in  ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with 4.7.2.3. The battery shall meet the requirements of 3.7.2.3.
