I. Menentukan diameter Twist.

D= 2 x d ( 1 )

D1= . D + d D1= d..( 2 )II. Menentukan diameter Quadd.y2= x2 x z2x= d( 3 )

z= d( 4 )

y2= d2 + d2y2= 2d2y= y= d atau . dD1= y = 1,414 . d

D= .d + y + 1/2d

= d + 1,414 d

= d ( 1 + 1, 414 )

= 2,414. d.

III. Menentukan die twist dan quad.

Die= D + 1

IV. Menentukan stranding.

= x insul x kV. Menentukan Die stranding :a). Press jelly=

Die={ x insul x k } + 0,5.VI. Menghitung panjang actual. Quad / Stranding ( Perpanjangan Quadd / Stranding ).

1 Bobbin 500 panjang twist = 5000 Mtr maka panjang actual single insul = 5000 x 1, 26 x 10-3 = 6,3 Mtr. ( Panjang actual insul = 5000 + 6,3 mtr = 5006,3 mtr.Contoh 2 : Quadd. insul 1,2, pitch = 75 mm

D1= 1, 414. d

= 1, 414 x 1,2

= 1, 697 mm

D= 2, 414. d

Contoh 3 :

: 75 mm

Pitch Stranding

: 500 mm

Panjang bobbin di quadd: 5000 M

Panjang bobbin di stranding: 3000 M

Panjang total insul: 11 + 5000 Mtr = 5011 Mtr,Stranding ;%=

D1=

= 20,72 mm

%=

= 8,438 x 10-3.Panjang quadd terhadap stranding: 8,438 x 10-3 x 3000 Mtr

: 25,3 ~ 26 Mtr.

Maka Panjang insul terhadap stranding: 26 + 3000 = 3026 Mtr,Perpanjang insul terhadap stranding: ( 8,438 x 10-3 + 2,187 x 10-3 ) x 3000

: 0, 0106 x 3000

: 31,875 Mtr.

Total insul terhadap stranding

: 3000 + 31,875 = 3031,875 Mtr.

Contoh:

% perpanjang total stranding

: % Stranding + % Quadd

: 8,438 x 10-3 + 2,187 x 10-3

: 0,0106

: 1, 06 %

Biasanya % yang dipakai di jembo = 2% ( untuk keamanan ).
