Product Description

Ⅰ. Introduction to Porcelain Casing Cable Termination

1. Porcelain Casing cable termination

Porcelain-sheathed terminals are high-grade electrical terminals. Its main parts include the terminal, porcelain sleeve, stress cone, cover for the stress cone, tail pipe, and others with insulating oil inside. The stress cones shall be made of high-performance electrical rubber while the porcelain sleeves shall be made of high-strength porcelain material to ensure excellent performance. This has a double layer in very important places which can fully play its role in preventing water from getting inside and also prevent oil from leaking during operation.

2. Composite Casing Cable Termination

The outside covering of composite-sheathed terminals includes epoxy glass fiber tubes plus an insulating rubber skirt. The rest of the structure matches that of porcelain-sheathed terminals. By using rubber as the outer material, these terminals provide excellent leakage and contamination resistance along with water repellency; thus, explosion hazards to personnel and equipment during accidents are minimized. Composite-insulated terminals weigh only 40% as much as porcelain-insulated terminals of the same voltage rating, making installation and transportation easier.

Ⅱ. Features of Porcelain Casing Cable Termination

1. Porcelain-Insulated Terminals

High-Strength Porcelain Sleeve: Utilizes a high-strength porcelain sleeve offering superior mechanical strength, excellent stability, and resistance to aging, making it particularly suitable for coastal areas and regions with harsh natural environments.

Umbrella Skirt Structure: Features an alternating large-small umbrella skirt design, proven through testing to deliver outstanding pollution resistance, suitable for pollution level IV areas.

Sealing Performance: The specially designed sealing structure ensures excellent sealing performance, eliminating potential defects such as water ingress and oil leakage.

Insulation Testing: All primary insulation components undergo factory testing per applicable standards.

2. Composite Sleeve Terminals

Epoxy Sleeve with Silicone Skirt: Epoxy sleeve externally covered with silicone skirt, internally filled with high-quality liquid compound. Suitable for densely populated areas and locations with concentrated electrical equipment.

Safety & Explosion-Proof: Safe and reliable with outstanding explosion-proof performance, posing no risk to personnel or nearby electrical equipment.

Lightweight and Easy Installation: Lightweight design facilitates straightforward installation.

Contamination Resistance and Aging Resistance: Excellent contamination resistance and external insulation aging resistance.

Insulation Testing: All major insulating components undergo factory testing per standard specifications.
