Automatic Splice
Splicing Connector Automatic Splice Full Tension Aluminum
Product Features
COTRAN automatic splice rated to hold a minimum 95% RBS of the Conductor used, can ensure quick and reliable overhead tension splice with fast and easy installation. The conductor simply slips into color-coded, funnel-shaped end piece and enters the pilot cap automatically with a simple push. The pilot cap guides the conductor to pass the set of serrated jaws and into the center of automatic splice.
Automatic splices are used on ACSR, AAC, AAAC conductor for an instant, positive and automatic connection, ANSI C119.4 Full Tension Class A connector.


Applications
Color-coded end piece provides instant visual identification of maximum conductor size
Funnel-shaped end piece quickly guides conductor into right position for insertion.
Pilot cap envelops strands and guides conductor pass serrated jaws and into splice center.
Precisely die-casted jaw provides optimum contact area for greater range of conductor sizes, reducing inventory stocking requirements.
Compressing stainless-steel spring positions jaws for positive conductor acceptance.
Tubular centers stop automatically determining proper insertion length of conductors.
High-strength, aluminum alloy tube covers connection for superior corrosion protection and lasting service life.

Enclosed is the instruction sheet, save time and eliminate potential for errors during installation.

Flexible Fireproof and Explosion-proof Blanket
Flexible Fireproof and Explosion-proof Blanket KC9001

KC9001 Flexible fireproof and explosion-proof blanket is suitable for the outer wrapping of the cable straight joint. It adopts multi-layer protective structure to cover the cable straight joint. The outer layer is made of ablation-resistant fireproof cloth with built-in flexible nano thermal insulation sheet and high strength aramid fiber cloth. When the fire broke out, the built-in can flexible nano can get insulation sheet is 3 ~ 4 times of that of the traditional performance, at the same time the highest heat resistance is above 1200 ℃, and it has excellent flame retardant and heat insulation effect, and the built-in high strength aramid fiber cloth can avoid the middle joint breakdown exploded the harm of adjacent cables, avoid the secondary damage caused by the fire. KC9001 light flexible fireproof blanket is easy to install, and it can be easily installed outside the cable intermediate connector after construction by means of pre-installed fire-resistant tie belt and D-type ring clasp without other tools.
