Thorne & Derrick Are Leading International Distributors Of Insulating Gloves

Insulating gloves offer personal protection for workers against electrical shocks when working near or on live wires and equipment. Each pair of electrical rubber insulating gloves must comply with the IEC 60903 and EN 60903 standards and as a result of this, each pair undergoes voltage, ageing and mechanical testing.

There are two main types of insulating gloves:-

  • Rubber gloves that provide very high dielectric properties which must be used in conjunction with leather gloves.
  • There is also gloves with mechanical properties that offer excellent mechanical protection against tears and punctures to eliminate the need for an over-glove.

The ergonomic design of CATU insulating gloves makes the product suitable for any type of hand and are soft and supple to enable excellent dexterity and usability. In addition there are sizes ranging from 7 – 12 in order to cover all requirements both male and female.

Other key features of the gloves include bi-colour to easily detect and abrasion, cut or tear to the gloves that could alter the dielectric properties of the product. There is also clear marking and a rolled cuff on some models to allow for easy handling.

Insulating Gloves – Selection And Application. How To Select The Correct Insulating Gloves

  • Class
    • The level of voltage protection required. Class ratings are
  • Product colour
    • If gloves need to be selected by their colour
  • Size
    • Product size between 7-12 for either male of female use
  • Class/Category
  • Classifications and standards

When selecting the correct insulating gloves all of the above factors are vital to consider in order to achieve the adequate level of protection required. In addition, some gloves will also require an under-glove for comfort or a leather over-glove to maintain product longevity.

Inspection and storage of insulating gloves is also a vital factor to consider as all gloves must be visibly inspected after each inflation and before each use. This is to make sure there are no tears or abrasion to the gloves prior to use, maintaining their dielectric properties.

CATU Insulating Gloves – Electrical Safety For UK DNO’s And LV HV Cable Contractors

T&D are approved vendors to most UK DNO’s and are able to help specify and advise on the correct insulating glove, voltage protection and type of glove required.

CATU Electrical Insulating Gloves For UK DNO's And UK Utilities

CATU Electrical Insulating Gloves For UK DNO’s And UK Utilities

For the UK utilities network, working with live lines and carrying out inspections on overhead lines is commonplace with this type of work being carried out daily. Electrical and worker safety is vital to prevent any arc flash explosions or electric accidents occurring.

Hot glove working traditionally consists of workers carrying out essential live line maintenance and over head line working to ensure uninterrupted supply of power. CATU insulating gloves provide the dielectric protection required for LV-HV cable jointing, live-line, substation, overhead and underground cable installations protecting against electrical shock.

Typical installations and work that require the protection provided by insulating gloves include:

  • Design of low and high voltage electrical systems
  • Cable laying (LV,11kV,33kV,132kV)
  • Cable jointing (dead LV, live LV,11kV, 33kV, 132kV)
  • Substation installation (up to 11kV/415V)
  • Overhead lines wooden pole and/or steel tower (up to 132kV)
  • Civil engineering works including excavation, cable laying and backfilling

CATU CG 35/2 Gloves Box is a UV resistant gloves storage box specially designed for protecting CATU insulating gloves. The CATU CG 35/2 Gloves Box can be fixed on walls, and bears recommended maintenance reminders.

Insulating gloves are to protect a LV-HV worker against electrocution whilst working in a potentially hazardous situation – the most common insulating glove material is natural latex.

Both CATU composite and rubber gloves are tested to IEC 60903. CATU electrical and pneumatic glove testing machines are available.

Rail Industry Focus: LV HV Overhead Live Line Work And Safety Insulation

Within the rail industry, low voltage cable jointing, switching, fusing and routine electrical maintenance on live lines are daily occurrences and require adequate electrical insulation protection.

Live line work is generally separated into three categories:

  1. Working at the contact – When working at the contact, insulating gloves provide the level of protection required from bare live parts where the protective equipment is adjusted to the voltage level. This method is generally used between 50V and 33kV.
  2. Safe clearance work – This method of working involves constantly maintaining a safe distance from the contact point whilst using insulating poles and insulating gloves for live work. This method is generally used between 400V and 225kV.
  3. The bare hand method – This method of working is resrved for very high voltage and involves the worker taking on the power of the line part being worked while protecting the worker from parts of different potential and from earth. This method is generally used between 225kV and 400kV. Whatever method is used, it is vital to wear individual protective equipment which is appropriate to the voltage level.
