This means they are two victories away from Färjestad's SHL record of 17 straight victories set 20 years ago.
When the two most dangerous teams in the series met, they took each other out for a long time.
At the beginning of the third, Skellefteå broke the deadlock when Måns Forsfjäll, 20, sent in 1-0 behind Emil Larmi in Växjökassen.
Tom Kühnhackl found his way to the unmarked Forsfjäll with a backhand.
In the stands, Forsfjäll's grandfather showed great joy over his grandson's first goal of the season.
In the middle of the period, Pär Lindholm got a clear free position, but Larmi was compliant and saved the puck with the leg guard.
A couple of seconds later, Forsfjäll shot from the blue after a back pass from Filip Sandberg in connection with a draw.
Larmi saved it but Joakim Lindström rushed forward and got the puck into the goal with his body for 2-0.
Växjö took out the goalkeeper and took a timeout in the final minutes.
In front of his own goal, Lindholm caught the puck and sent it straight across the court into the open Växjökassen for 3-0.
