MacLean Power Systems ACRS CRS Connector

CRS splice3.png

The splice greatly reduces field problems: first the VIP feature should eliminate partial wire insertions (a prime cause of connection failures). The VIP feature signifies proper insertion even in nighttime darkness or storm situations, thereby allowing crews to get the job done quickly and correct.

Secondly, the high performance corrosion inhibitor greatly reduces splice failures due to corrosion. In comparison to compression splices: automatic splices like the CRS are faster to install with less support equipment required. This equates to lower installation costs and quicker storm recovery.

FEATURES

  • New synthetic inhibitor with wide temperature range for improved corrosion protection
  • Pop up tab to verify proper insertion
  • Ventilation holes to allow moisture to escape and for air cooling
  • Stainless steel spring & aluminum pilot cup to improve corrosion performance
  • Rated to hold a minimum of 95% of RBS of the conductor used
  • ANSI C119.4 Full Tension Class A connector

CORROSION TESTS

Accelerated harsh environment test: 

  1. Place samples in salt fog chamber. Soak for 22 hours
  2. Place samples in oven at 100ºc. Soak for 1 hour
  3. Remove samples from oven and immediately dunk in water bath
  4. Allow to cool to room temperature for 1 hour
  5. Repeat steps 1-4 for 22 days
  6. Section parts for inspection

Typical test results:

corrosion5.png
  • Corrosion and red rust on spring approx 50% of surface area
  • Moderate amounts of red rust on pilot cup
  • Oxidation and pitting on jaws, approx 75%
  • Buildup of salt crystals on center barrier and jaws

CRS Test Results:

  • No corrosion on spring or pilot cup
  • No oxidation on jaws
  • No buildup of salt crystals

THE VIP (VISUAL INDICATOR PROJECTION) FEATURE

The CRS comes with two 2 pop up tabs, which serve as visual indication of a complete insertion. Do not stop pushing conductor or release come-a-long until pop up tab is activated. Also, the pop up tab is not a release so the splice can be safely pulled through a block.
