Types of Other Cable Accessories

110kV Cable Direct Grounding Box
The 110kV cable direct grounding box is a critical component in high-voltage cable systems, designed to directly ground the metallic shielding layer of cables. It can safely dissipating currents, suppressing power-frequency overvoltages, and preventing insulation breakdown risks.

Cable Protection Earthing Box
The cable protection earthing box is a device designed to provide grounding protection for cables,by connecting the cables to the ground,the earthing box ensures that fault currents can be quickly dissipated,reducing the risk of equipment damage.Typically,the box is equipped with multiple grounding terminals to accommodate various cable types.

15kV/630A European-Style Rear Connector
The 15kV/630A European-style rear connector (also known as a European-style cable rear connector or European-style rear bushing) is a fully insulated, fully shielded plug-in cable connection device used in medium-voltage (12/15kV) power distribution systems. It is primarily applied in ring main units (RMUs), compact substations, and cable distribution cabinets for cable entry and exit connections.

15kV/630A European Style Front Coupler
15kV/630A European style front coupler is a high-voltage, high-current electrical connector designed for medium-voltage (MV) power distribution,this product is designed to directly connect with the bushings of switchgear in/outgoing lines or wall bushings of cable distribution boxes, providing fully insulated and safe circuitry for switchgear and cable distribution boxes.

Precautions for Using Other Cable Accessories

Inspect portable cord-and-plug connected equipment, extension cords, power bars, charging stations, and electrical fittings for damage or wear before each use. Repair or replace damaged equipment immediately.
Always tape extension cords to walls or floors when necessary. Do not use nails and staples as they can damage the cords and cause fire and shocks.
Use extension cords or equipment that is rated for the level of amperage or wattage that you are using.
Always use the correct size fuse. Replacing a fuse with one of a larger size can cause excessive currents in the wiring and possibly start a fire.
Be aware that unusually warm or hot outlets or cords may be a sign that unsafe wiring conditions exist. Unplug any cords or extension cords from these outlets and do not use them until a qualified electrician has checked the wiring.
Always use ladders made with non-conductive side rails (e.g., fibreglass) when working with or near electricity or power lines.
Place halogen lights away from combustible materials such as cloths or curtains. Halogen lamps can become very hot and may be a fire hazard.
The risk of electric shock is greater in areas that are wet or damp. Install Ground Fault Circuit Interrupters (GFCIs) as they will interrupt the electrical circuit before a current sufficient to cause death or serious injury occurs.
Use a portable in-line Ground Fault Circuit Interrupter (GFCI) if you are not certain that the receptacle you are plugging your extension cord into is GFCI protected.
Make sure that exposed receptacle boxes are made of non-conductive materials.
Know where the panel and circuit breakers are located in case of an emergency.
Label all circuit breakers and fuse boxes clearly. Each switch should be positively identified as to which outlet or appliance it is for.
Do not use outlets or cords that have exposed wiring.
Do not use portable cord-and-plug connected power tools if the guards are removed.
Do not block access to panels and circuit breakers, or fuse boxes.
Do not touch a person or electrical apparatus in the event of an electrical incident. Always disconnect the power source first.
Make sure electrical tools and equipment have a certification marking from an accredited agency accepted by your jurisdiction (e.g., UL, ULC, CSA, ETL). Be careful when purchasing equipment from another country or online, as they may not be approved.
Make sure only qualified individuals work on or perform maintenance on electrical equipment (e.g., electricians).
