This page compiles electrical cable-ladder and fitting drawings used by The Sun for consultation, specification coordination and project manufacturing. Engineers can refer to straight-ladder construction, joint-hole patterns, horizontal and vertical bends, tees, crosses and reducers.
Check drawing dimensions against width W, height H, straight-section length, bend radius, material thickness, cable load and support spacing for each project. When ordering, provide route drawings or a bill of quantities so The Sun can verify compatibility between straight ladders and fittings.

Straight Cable-Ladder Drawings and Joint-Hole Types




Note: The default joint-hole type at The Sun is Type 1 (for heights < 150 mm). Please specify joint-hole types 2, 3 or 4 when placing a special order.
Cable-Ladder Fitting Drawings (Bends, Tees and Crosses)














Note: Unless otherwise requested, The Sun manufactures bends, tees and crosses in the standard configuration (the best-looking configuration)

Straight cable-ladder ordering code
Product code: TC-WxHxT-N-LN-XXX
Where:
W: Width (mm)
H: Height (mm)
T: Thickness (mm)
N= CN: With cover
N= KN: Without cover
N= ND: Cover only (no ladder body)
LN= LN1: Joint-hole type 1 (see joint-hole types below)
LN= LN2: Joint-hole type 2
LN= LN3: Joint-hole type 3
XXX= STD : Powder coating
XXX= TTK : Pre-galvanized steel
XXX= KNN : Hot-dip galvanizing
XXX= INO : 304 stainless steel
XXX= HKN : Aluminium alloy
Example:
TC-200x100x1.2-CN-LN1-STD : Cable ladder 200mm(wide)x100mm(high)x1.2mm(thick) with cover, joint-hole type 1, powder coating.
TC-300x100x2-KN-LN2-KNN: Cable ladder 300mm(wide)x100mm(high)x2.0mm(thick) without cover, joint-hole type 2, hot-dip galvanizing
Fitting ordering code
Fitting code: TC-PK-WxHxTxR-N-LN-XXX
Where:
PK= CN: Horizontal bend
PK= CL: Riser bend
PK= CX: Drop-out bend
PK= TE: Tee
PK= TH: Cross
PK= GD: Symmetrical reducer
PK= GT: Left-hand reducer
PK= GP: Right-hand reducer
W: Width (mm)
H: Height (mm)
T: Thickness (mm)
R: Corner radius as required. Without parameter R, the angle follows The Sun’s default standard.
N= CN: With cover
N= KN: Without cover
N= ND: Cover only (no ladder body)
LN= LN1: Joint-hole type 1 (see joint-hole types above)
LN= LN2: Joint-hole type 2
LN= LN3: Joint-hole type 3
XXX= STD : Powder coating
XXX= TTK : Pre-galvanized steel
XXX= KNN : Hot-dip galvanizing
XXX= INO : 304 stainless steel
XXX= HKN : Aluminium alloy
