TSTM CONDUCTOR (AN ENABLING TECHNOLOGY)

Conductor Constituents

 Options for Aluminium (CONDUCTIVITY) 

 Options for Core (STRENGTH)

 

 

ACSR – A Century Old Technology

ACSR Deficiency：Strength、Thermal Sag、Ampacity、Line Loss

 

一、Steel as Strength Member，Limited Strength Need Hard Aluminum：Resistance High, Temp Limited 二、Self Weight，Thermal Sag Steel High CTE，Conductor Serious Thermal Sag 三、Limited Ampacity，High Line Loss Temp Limited（＜90℃） High Resistance; Large Line Loss 四、Longevity Subjected to Environmental Degradation

Conductor Example: ACSR vs CFCC (capacity、loss、sag)

ACSR 100+ yrs Technology • Broadly Used (>95% • Safe & Reliable • Grid 1st Choice • Large Sag, Temp limited to <90 C

CFCC 90s, Japanese Technology & Goldsworthy 2002 ACCC from CTC Cable 2005 Deployment Emergence of ACCC like Chinese products (2010) Other Variants - Mercury, Nexans, Southwire, De Angeli

CFCC Advantage (High Temp, Low Sag, High Ampacity, High Efficiency) • 2x Capacity    • Line Loss Reduced by 30%     • Same Size Conductor: More Aluminum

 

CFCC Special Fitting、Core Breaking

一、Special Fitting (High Cost: 5ⅹ、Training)

二、Vulnerability to Bending & Compression (especially Sharp Angle Bending)

Failed ‘Composite’ Concepts to Replace ACSR

 

MFG: Product:	CTC & Chinese  ACCC	Mercury HVCRC	Nexans Lo-Sag	CFCC/C7 Southwire	De Angeli CFCC/C	3M ACCR
Flaws:	Glass Outer Layer Single Rod Low Modulus Expensive Fittings Costly	Glass Outer Layer Glass Center Single Rod	Thin Al Clad No Glass Single Rod	Multi Core Strands No Glass; TP Matrix Thin Al Ribbon	Multi Core Strands No Glass; Insulation  Thin Al Clad	Ceramic Outer  Brittle Expensive  Fittings Costly

All CFCC Composite Core Options Are: Fragile and Vulnerable Due to Environmental Degradation and Bending Failures  Costly, Unreliable, and Incompatible with Standard Industry Work Practices Limited in Field Applications - Significant Ice Sag, No Distribution Application

 

Other HTLS Conductor Examples: ACCR, ACSS, INVAR, GAP Options

Desired Attributes for Conductors

 

No Conductor Meets All the Five Requirements! 

 

CFCC Issues (Safety、Longevity、Cost、Ice Sag)

A、The Glass Layer in Core (Preventing Galvanic Corrosion)

Thermal RESIDUAL Stresses, 

I.  CORE Strength Degradation over time (Glass Layer under Tension, Stress Corrosion Fatigue)

II. Carbon Core under Compression, more Vulnerable to Bending Failure

Low Modulus in Core and Conductor, 

I.  Excessive Sag in Large Ice Load

II. Excessive Sag with Larger and Heavier Conductor, and in Long Span

B、Safety Suspect (Vulnerable to Bending Break); Expensive Fitting and Installation

• Vulnerable to Axial Compression (Bending Damage in Manufacturing, Storage & Installation)
• Undetectable Bending Breakage to core; Expensive Installation
• Radial Compression Damage, Slippery Core; Wire Edge Grinding into Core; Expensive Special Fitting

C、Longevity Suspect (Subject to Environmental Degradation) 

• Core Exposed to Environment (Gaps in Aluminum strands), Longevity Impact
• Air (Resin Thermal Oxidation), Moisture (Hydrolysis), UV and Ozone (Resin Degradation), etc.
• Tension and High Temp Operation Exasperate the Core Degradation

 

TSTM , the Enabling Conductor Technology

一、Desired Stress Condition in Core, via Aluminum Encapsulation

• Guaranteed Reliability: Eliminated sharp angle occurrence; Improved resistance to bending damage. 
• Guaranteed Longevity: Shielded composite core from environment.
• Reduced Project Cost: Encapsulated core is fully compatible with ACSR type hardware and easy to install.

• Enhanced Performance: More Aluminum; Further improved Ampacity, energy Efficiency, conductor Strength and Modulus. Also Suitable for heavy ice and ultralong span applications

二、Patented Technology

• PATENTS Granted in US & China; Pending in Vietnam, India, Indonesia, Europe, Africa etc.
• TSTM, The Enabling Technology, addressed all remaining issues of CFCC conductors (Safety & Reliability, Longevity, Compatibility, Cost, and Performance)
• DOES NOT INFRINGE ANY Existing Patent (Core, Conductor or Hardware)
